Nuclear: Energy from atomic reactions.
Thermal: Heat-based energy generation.
New and renewable energy: Sustainable energy sources.
Hydro: Energy from water flow.
Correct sequence: Thermal (B) > Hydro (D) > New and renewable energy (C) > Nuclear (A)
Explanation: Thermal power plants use heat to generate electricity, making them a major source. Hydro power utilizes flowing water, ranking next. New and renewable energy sources, like solar and wind, follow. Finally, nuclear energy, while significant, has a lower capacity compared to the others in India.
