Answer:
B. river - reservoir - channel - turbine - generator
Explanation:
Hydel energy power plant is working as the principle of converting from kinetic energy to electrical energy. River water flows through their path, reservoir built across the path in order to save it. Then built the construction of hydel powerplant which consists a long narrow path flow which is known as Channel. Water flows through desired pressure and velocity and it makes the rotatory motion of turbine which is coupled with generator. Generator works as the principle of converting mechanical energy to electrical energy.
