The correct option is (c) Pumped storage plant

Easiest explanation: Reversible turbine has been devised for heads varying between 15 to 90 m that can function both as a turbine as well as a pump. This provision helps considerably in improving the load factor of the power system. They can work at relatively high efficiencies and helps in cost reduction.
