C Correct answer
Explanation

This is incorrect. Evaporation is a type of vaporisation of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance. The temperature at which saturation occurs in a given sample of air is known as dew point. Thus, dew point is not a type of vaporization of a liquid.
