Q.

Hailstorms are caused due to:
Explanation:

ANS. (D) 
In a hailstorm, small ice particles that form above the freezing level (which occurs in all thunderstorms) collect either rain water or cloud water on them, forming a water shell that freezes. The tilted updraft and downdraft structure of the storm is important in order for hailstones to grow because they can be ‘recycled’ several times, until they either become too large for the updraft to carry them, or they get caught in a downdraft, and they finally reach the ground.
