Which cloud type is confined to the middle height range?

A. cumulonimbus

B. cirrus

C. cirrostratus

D. altostratus

Answer:

D. Altostratus

Explanation:

Altostratus cloud is a type of physical stratiform: a cloud which can be identified by its gray or blueish gray colour. It is a middle level cloud, that is associated with a storm and excessive rain or snow. It contains ice crystals and water droplets, and it is lighter in colour when compared to nimbostratus, while it is darker in appearance when compared to cirrostratus.

It would be alto. I hope that is one of your answers.
