Final answer:
The correct statement about hail is that it may freeze at high elevations many times before falling to the earth. Hailstones form in thunderstorm clouds and gain more layers of ice as they ascend and descend in the cloud multiple times.
Step-by-step explanation:
The correct statement about hail is option b: it may freeze at high elevations many times before falling to the earth. Hail forms in thunderstorm clouds, particularly those with intense upward air movement (updrafts). When small ice pellets get pulled into the updraft, they may ascend and descend multiple times in the cloud, each time accumulating more layers of ice before they eventually grow too heavy and fall to the ground as hailstones.
