Option (B) is correct.

Explanation:

In a coal fired power plant, first the coal if burnt.

The energy transformations are give below.

Chemical energy of coal is converted into heat energy. (Burning of coal)

Heat energy is used to heat the water and to form steam.

By taking the energy from steam, the turbines rotate. In this step, the heat energy is converted into mechanical energy.

Finally, the mechanical energy is used to rotate the coil of generator and converts into electrical energy.

it is the second option.
