The correct answer is: A. Diesel power plants.
Diesel power plants are the least common type of power plant in India, providing only 1% of the country’s electricity. They are used in remote areas where there is no access to the grid, or as backup power during outages. Diesel power plants are expensive to operate and maintain, and they produce high levels of pollution.
Thermal power plants are the most common type of power plant in India, providing 60% of the country’s electricity. They use coal, oil, or natural gas to generate electricity. Thermal power plants are relatively inexpensive to build and operate, but they produce high levels of pollution.
Hydro-electric power plants are the second most common type of power plant in India, providing 15% of the country’s electricity. They use the power of moving water to generate electricity. Hydro-electric power plants are clean and efficient, but they can only be built in certain locations.
Nuclear power plants are the least common type of power plant in India, providing 3% of the country’s electricity. They use nuclear fission to generate electricity. Nuclear power plants are clean and efficient, but they are also expensive to build and operate.
