Correct option is C
1. Steam Power Plant:
· Typically uses coal, natural gas, or oil as fuel.
· Transportation of these fuels can be costly, especially if the power plant is far from the fuel source.
2. Hydroelectric Power Plant:
· Uses water as the energy source.
· There are no fuel transportation costs since the energy source (water) is naturally available at the location.
3. Diesel Power Plant:
· Uses diesel fuel, which can be expensive to transport, especially over long distances.
4. Nuclear Power Plant:
· Uses uranium or other radioactive materials.
· Transportation of nuclear fuel is highly regulated and can be very costly due to safety and security measures.
Therefore, the correct answer is (c) hydroelectric; steam.
