The correct option is<u> B. in areas where reservoirs of water are heated inside earth</u>
Explanation:
The geothermal power plants use the geothermal energy of the Earth to produce electricity. The heat from the core of the Earth is used to heat water. The heated water is used to turn a generator or a turbine. And then the cooled water is drained back into the Earth's core.
The energy used by geothermal power plants can be considered to be renewable as the core of the Earth's crust have enormous heat energy and only a little is used up for this process.
