Solution
The correct option is A II and III
As a fuel, hydrogen is very difficult to store. It is extremely reactive and it combines with most of the metals and non-metals forming stable compounds. Thus it is not available in the free state.
On the other hand, the calorific value of H2 is very high - 150 KJ/g, and so can be very useful as a fuel.
Similarly, it is an extremely clean fuel that releases only water upon combustion. Thus, cleanliness doesn't hinder its usefullness either.
