Which cloud is linked with rain-giving clouds by name?

Correct answer: Nimbus

Direct answer: D, nimbus. In cloud terminology, “nimbus” or “nimbo-” is associated with precipitation or rain-bearing clouds. For example, nimbostratus is a widespread layered cloud that can produce prolonged rain, while cumulonimbus can produce heavy showers, thunderstorms and sometimes hail. A, cirrus, describes high, thin, wispy clouds and does not itself mean rain-bearing. B, cumulus, refers to a heap-like or piled-up appearance; ordinary cumulus may occur in fair weather, although it can develop further under suitable conditions. C, stratus, means a layered or sheet-like cloud form, but the word alone does not specifically indicate rainfall. Therefore the question asks for the name-based clue, not the claim that every cloud containing the word nimbus produces identical weather. The safest memory cue is: nimbus means rain-bearing; stratus means layered; cumulus means heap-like; cirrus means wispy and high.
