Solution

The correct option is A Both the statement and the reason are true and the reason is the correct explanation.
Water vapour has more energy than boiling water, although both are at the same temperature. It is due to the high of latent heat of vaporization in water vapour. Hence more burning sensation is caused by water vapour.
