Explanation / Answer

Heat energy released from the burning of coal is converted into mechanical energy which then converted into electricity .

option (1) is correct.

burning of coal releases heat energy which is used to generate the steam . stem is used to run the steam turbine which is coupled to an alternator which generates the electricity. therefore heat energy is converted to mechanical energy through turbine and mechanical energy converted to electrical energy through alternator or generator.
