✓
Answer
Correct option: C.
Has very high calorific value.
Hydrogen has the highest calorific value among all the substances found on earth $(150kJ/ g)$. Moreover, it has low ignition temperature. Therefore, when it is ignited, it reacts explosively with oxygen. Thus, it is very unsafe to use and is not considered as a good fuel.
