Answer:
Option C.
Explanation:
LPG is the right answer.
The volume of energy generated by the entire flaming of a substance or fuel is known as the calorific value. It is estimated in units of energy per volume of a substance, for example, kJ/kg. Among the given options LPG is the right answer because the calorific value of LPG is 55000 kJ/kg. It implies that if 1 kg of LPG is smoked entirely, then it will generate 55000 kilo-joules of heat potential.
