Solution

The correct option is B Liquid A has higher latent heat of vaporization than that of liquid B
A drop each of two non-corrosive and non-irritating liquids A and B at a temperature of 22 $^{o} C$ are placed on the skin. Liquid A gives a more cooling sensation than liquid B.

Liquid A has a higher latent heat of vaporization than that of liquid B. Due to this, more heat is absorbed from body during vapourisation of liquid A than during vapourisation of liquid B.

Hence, the correct option is $B$
