C)large numbers of supercooled droplets.
D)large numbers of particulates.

Question

Hail formation requires the presence of supercooled water droplets, which are liquid droplets that exist at temperatures below freezing. These droplets are necessary because they act as nuclei for ice crystals to form around. Without a sufficient number of supercooled droplets, hailstones cannot form. Strong upward vertical motion is also necessary for hail formation because it helps to lift the developing hailstones up into the colder regions of the cloud where they can continue to grow. warm temperatures at high levels in the cloud would actually inhibit hail formation, as it would promote the melting of any ice crystals that do form. The presence of large raindrops or particulates is not necessarily a factor in hail formation.
