The correct answer is A) Thermal power generation.
Coal is a fossil fuel that is used to generate electricity. It is the most abundant fossil fuel in the world, and it is used in about 40% of the world’s electricity generation. Coal is also used to make steel, and it is used in some industrial processes.
Thermal power plants use coal to generate electricity. The coal is burned in a furnace, and the heat from the burning coal is used to boil water. The steam from the boiling water is then used to turn a turbine, which generates electricity.
Telangana is a state in India that has significant coal reserves. The coal in Telangana is mainly used for thermal power generation. The state has several thermal power plants that use coal to generate electricity. The electricity generated by these plants is used to power homes, businesses, and industries in Telangana.
