Answer : Option C
Explanation :
Saturation vapour pressure increases with rising temperature. Saturation vapour pressure just above liquid water is greater than that over ice. At temperatures below freezing it takes more vapour molecules to saturate air directly above water than it does to saturate air directly above ice.
