Solution

The correct option is A
Cyclisation of the molecules

Intramolecular hydrogen bonding is formed between the hydrogen atom and highly electronegative atom present within the same molecule. It results in cyclisation of the molecules and prevents their association. So its effect on the physical properties is negligible.
