Question 1198Navigation General

The correct answer is C) mamma. Mamma, also known as mammatus clouds, are the small, visible mound-like protuberances that can form on the underside of cumulonimbus (thunderstorm) clouds. These cloud formations are potential breeding grounds for waterspouts and tornadoes, as they indicate unstable atmospheric conditions. The other answer choices are incorrect - rime is a type of ice formation, thunderheads is a general term for cumulonimbus clouds, and ice prisms are a different cloud formation not specifically associated with potential for severe weather.
