Which weather phenomenon may accompany precipitation falling from a cumulonimbus cloud?

A cloud will form Observing wind direction Lightning and thunder 500 feet below a cloud

Correct Answer:

Lightning and thunder

Explanation:

Cumulonimbus clouds are thunderstorms, and they commonly bring both heavy precipitation and electrical activity. The strong updrafts and collisions of ice particles inside these clouds create charge separation, which leads to lightning; the rapid heating and expansion of air from that lightning then produces thunder. The other options don’t describe a weather phenomenon specifically tied to rain from a cumulonimbus cloud—forming a cloud, observing wind direction, or a distance below the cloud aren’t phenomena that accompany the precipitation in this context. So lightning and thunder is the best match.
