Right choice is (a) true

Easy explanation: Oxygen is present in combined form with hydrgen in the coal. It is very difficult to break hydrogen-oxygen bond and hence, that combined form of hydrogen is not available for combustion. Thus, free hydrogen available for combustion is lesser than the actual one.
