Solution

The correct option is C Electrical energy - Heat energy - Mechanical energy
Electricity is used to heat water into steam. This step involves the conversion of electrical energy into the heat/thermal energy. This steam spins the blades of the turbine. As the heat energy produced in the earlier step is being used to cause the physical movement of the turbine, it gets converted to mechanical energy of the turbine.
