Solution

The correct option is A Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I.
Option A is the correct answer.
Water molecule contains a highly electronegative Oxygen atom in it. Thus water molecules are engaged in extensive intermolecular hydrogen bonding with their nearest water molecules. And thus a bulky molecule is formed.
High amount of energy is required to dissociate these bonds and hence water molecules have a higher boiling point than expected.
