Hydroelectric power is produced using the energy of moving water. how is this process accomplished

The correct answer is option C which is the water flows downstream into the reservoir behind the dam.

Explanation:Hydroelectric power is the generation of energy from the water.Actually it uses the kinetic energy from the flowing water to run the turbines which are linked to the generators.Then generators converts this kinetic energy into electric energy.The water always moves from the higher potential to the lower potential which cause the transfer of kinetic energy into mechanical energy to run turbines.It is the movement of water in downstream.

What are the options? physical property can be color, smell, opacity, viscosity, density, infra red spectrum, melting and boiling points, attraction and repulson to magnets, etc.
