In which condition is widespread slow rain more likely than sudden hailstorm?

Correct answer: Layered nimbostratus clouds are present

Direct answer: A. Nimbostratus is a broad, layered cloud type commonly associated with widespread, steady, and often long-lasting precipitation. Its structure usually produces gradual rain over a large area rather than the abrupt, highly localized conditions of a hailstorm. A is correct because the question asks for slow, widespread rain. B is wrong because strong updrafts in cumulonimbus clouds support vigorous convection and can carry ice particles upward repeatedly, helping hail form. C is wrong because circulating large hail is already evidence of a hail-producing storm, not a condition favouring ordinary widespread slow rain. D is wrong because very unstable air favours rapid vertical development, thunderstorms, strong showers, and possibly hail. A nimbostratus cloud may still produce heavy rain in some situations, but its characteristic association is persistent layered precipitation. Memory cue: nimbostratus means broad and steady rain; cumulonimbus means towering, sudden, convective weather.
