B Correct answer
Explanation

Hail forms when moist air rises rapidly and cools quickly, causing water droplets to freeze before falling. This is different from frost (forms on cold surfaces), fog (near-ground cloud), or snow (gentle freezing of falling crystals). The key is the rapid ascent causing quick freezing, which is characteristic of hail formation.
