The correct option is C Hail
Hail
is a small ball of ice in the atmosphere, especially at night. It is a result
of precipitation. It is produced by intense thunderstorms when snow and rain
coexists. As the snowflakes fall, liquid water freezes onto them. It forms ice
pellets that continue to grow as more droplets accumulate. When the ball of ice
becomes so large and heavy, they fall as hailstones.
