Why Are Raindrops Larger Than 5 Millimeters Rare

Why are raindrops larger than 5 millimeters rare?

A) Because they start as snowflakes, they must grow much larger than 5 millimeters while falling from a cloud without sublimating.
B) The frictional drag from falling is greater than the surface tension that holds the drops together when they get larger than 5 millimeters.
C) If they form larger than 5 millimeters then they will reach the ground as snow or hail instead of rain because they cannot melt completely.
D) There is no process to form large raindrops in clouds.
