Which combination of the following terms is matched correctly?

I) Vapour pressure

II) Intermolecular forces

III) Latent heat of vaporization

We know that vapour pressure is inversely proportional to intermolecular forces so if intermolecular forces are strong then rate of evaporation will be very low.

Thus, when the vapour pressure is high intermolecular forces are low and if intermolecular forces are low then small heat is required to convert liquid into vapour.

Hence, option(a) is correct.
