Solution

The correct option is A True
Inter molecular force is directly proportional to the boiling point of liquid which means if inter molecular forces between the molecule are strong then the boiling point will be high.
The stronger the intermolecular forces the lower the vapour pressure of substance and higher the boiling point.
Therefore, the given statement is true i.e., Boiling point of liquid is a measure of the strength of inter molecular forces between its molecule.
