Statement C is NOT correct.

Hailstones form within strong thunderstorms (cumulonimbus clouds). They require strong updrafts that carry water droplets high into the freezing parts of the cloud where they accrete ice. Hailstones grow by repeatedly being lifted and falling through layers with supercooled water before eventually becoming too heavy and falling to the ground. Statement C incorrectly describes rain from warmer upper layers solidifying in lower subfreezing layers; in reality, ice forms and grows in the cold upper parts and can melt as it falls through warmer lower parts, but hailstones are defined as reaching the ground as ice.

Hailstones are characterized by their layered structure, indicating growth by accretion of ice in different conditions. They are indeed associated with intense cumulonimbus clouds. While hailstorms can occur during the monsoon, they are not exclusively or “usually” limited to that season and are common in other thunderstorm-prone periods like pre-monsoon.
