Solution

The correct option is A 4 kg of fuel will release 1,00,000 kJ of energy on complete combustion.
Calorific value is the amount of heat energy produced on complete combustion of 1 kg of fuel.
That implies 1 kg of fuel gives 25,000 kJ of energy. Similarly, 4 kg of fuel will give 1,00,000 kJ of energy.
