Best answer
Correct choice is (c) H2O

The best explanation: Hydrogen present in the form of moisture does not undergo combustion that is why the combined hydrogen present in coal does not undergo combustion. It is only available hydrogen which is equivalent to (H-O/8) that takes part in combustion.
