Which cloud pair is mentioned as being named?

• A. Cirrus and Nimbus
• B. Altostratus and Nimbostratus
• C. Cumulus and Cirrus
• D. Stratus and Cumulus

Answer: (D)

In cloud naming, many forms have their own distinct names, with two classic, independently named cloud types being Stratus and Cumulus. Stratus clouds form those broad, gray layers that drape across the sky, while Cumulus clouds appear as fluffy, rounded puffs with vertical growth. Both are standard named cloud genera you’ll see in introductory weather material, so they clearly illustrate two separate, named cloud forms. The other options mix terms that aren’t standalone cloud types in the same way—Nimbus is usually used as part of compound names for rain-bearing clouds, and some pairs combine more specialized forms that aren’t as commonly presented together as simple named clouds.
