The correct answer is chemical energy.

Key Points

• The dry cell is a type of electric battery which is used for portable electrical devices.
• Electricity is produced through the dry cells from electrochemical energy. Hence, Option 1 is correct.
• A common dry cell is a zinc-carbon cell.
• The electrolyte is immobilized as a paste by a dry cell, with just enough humidity in it to allow current to flow.
• Like a wet cell, a dry cell can work without spilling in any direction, because there is no free liquid in it.
• The versatility makes it ideal for mobile devices.
• The first wet-cell batteries, in comparison, were usually fragile glass containers featuring lead rods sticking from an open-top.
• Hence, they required careful handling to prevent spillage.
• The dry-cell battery development made a significant advance in battery safety and portability.
• Batteries render electricity from chemical energy.
• Batteries consist of one or more different parts, or cells, which contain an electrolyte called a chemical.
• Every cell has two electrodes that are electrically conductive immersed in its electrolyte.
• The electrodes consist of different materials; one releases electrons into the electrolyte, and the other absorbs them.
• Once an electrical system is attached to the electrodes, an electrical current passes through it and supports its operation with electric power.
• The energy contained in the dry cell is therefore in the form of chemical energy.

Additional Information

• Thermal energy
  • It is also called heat energy 
  • It is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other.
  • The energy that comes from the temperature of the heated substance is called thermal energy.
  • Thermal energy is energy that comes from a substance whose molecules and atoms are vibrating faster due to a temperature rise.
• In physical sciences, mechanical energy
  • It is the sum of potential energy and kinetic energy.
  • It is the macroscopic energy associated with a system.
  • The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant.
• Nuclear power
  • It is the use of nuclear reactions to produce electricity.
  • Nuclear power can be obtained from nuclear fission, nuclear decay, and nuclear fusion reactions.
  • Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants.

The correct answer is Feldspar.

Key Points

• Rajasthan was the leading producing state of Feldspar contributing 61% of the total production followed by Andhra Pradesh (34%).
• Rajasthan is leading producer of:
  • Lead and Zinc
  • Feldspar
  • Wollastonite
  • Silver
  • Rock Phosphate
  • Gypsum
  • Red Ochre

Additional Information

• Lignite Mineral:
  • The state of Rajasthan is endowed with large lignite deposits in the country after Tamilnadu & Gujarat. In the three districts of the state viz. RSMML at present is operating.
  • Two lignite mines one at Giral in district Barmer and another at Kasnau-Matasukh in district Nagaur.
• Copper Mineral:
  • Second: Rank of Rajasthan in Copper Production in India.
  • Most important Copper reserves in India:
  • Malanjkhand, Balaghat, Madhya Pradesh (makes MP, 1st in Production).
• Iron Mineral:
  • Ore: Found in Dharwad and Cuddapah rock systems of peninsular India.
  • Ore Quality-wise ranking: Haematite > Magnetite > Limonite > Siderite
  • Largest Deposit in India: Barabil-Koira Valley in Odisha.
  • Deposits of Iron-Ore in Rajasthan.
  • Jaipur - Morija-banol - Neemla-Raisalo.
  • Bhilwara - Pur banera belt.
  • Udaipur - Natha ki Pal, Thur Hunder.

Here the pattern is,

Hypertext transfer protocol (HTTP):

• HTTP is used to access data on the world wide web. HTTP functions as a combination of FTP and SMTP. HTTP uses the services of TCP port number 80. HTTP is a stateless protocol.
• HTTP prior to version 1.1 specified a non-persistent connection, while a persistent connection is a default.
• In a non-persistent connection, one TCP connection is made for each request/ response. The client opens a TCP connection and sends a request and server sends the response then closes the connection.

File Transfer Protocol (FTP):

• FTP stands for file transfer protocol. It is provided by TCP/IP for copying a file from one host to another. FTP can transfer a file through one of the following three modes: stream mode, block mode and compressed mode. Stream mode is the default mode.
• FTP uses two TCP connections one for data and another for control.

Simple Transfer Protocol (SMTP):

• SMTP is a push protocol, it can push the messages from the client to the server only.
• SMTP uses one TCP connection at a time

TELNET:

• TELNET is a client/ server application that allows a user to log on to a remote machine, giving the user access to the remote system.
• TELNET uses one TCP connection at a time.

Important Point:

Option 1 is not correct since HTTP might have more than one TCP connections for a single web page.

The logic here is,

PRANIC : SQOBDJ

Similarly,

SORBID : ?

Hence, "PTCSEJ" is the correct answer.
