Explanation
The question requires the understanding of energy transformations in a hydroelectric power plant. The first step in energy transformation in a hydroelectric power plant is the transformation of gravitational potential energy when the water in the reservoir possibly located at a height is withdrawn and it falls under scale of natural/gravitational forces. Then, water falling onto the turbine blades causes them to spin which transforms the gravitational energy into kinetic energy, the energy of movement (this includes operational energy for the turbine). The turbine is now connected to a generator which spins a magnet inside a coil inducing voltage in it. This continues until kinetic energy transforms into electrical energy being the final form easy to transmit and distribute to grid lines. Recalling energy types list given in question brings us to:a = gravitational energyb = kinetic energyc = electric energyTherefore, the correct answer will be a - gravitational energy, b - kinetic energy, and c - electric energy.
