Solution

The correct option is B
larger amount of potential energy is converted into kinetic energy

The energy conversion that takes place in a hydroelectric power plant is the following:
The potential energy of still water is changed into kinetic energy when water is allowed to flow down. Then, this kinetic energy is converted to electrical energy by means of a turbine and a generator connected to the turbine

More electrical power can be generated by a hydroelectric power plant if water falls from a greater height because a larger amount of potential energy is converted into kinetic energy.
