(b) Stratus
(c) Cirrus​

Answer 1

Answer:

(c) Cirrus is the correct option.

Explanation:

Cirrus clouds are delicate, feathery clouds that are made mostly of ice crystals. Their wispy shape comes from wind currents which twist and spread the ice crystals into strands.

Cirrus (cloud classification symbol: Ci) is a genus of atmospheric cloud generally characterized by thin, wispy strands, giving the type its name from the Latin word cirrus, meaning a ringlet or curling lock of hair.[1] Such a cloud can form at any altitude between 5,000 and 13,700 m (16,500 and 45,000 ft) above sea level. The strands of cloud sometimes appear in tufts of a distinctive form referred to by the common name of "mares' tails".[2]

From the surface of Earth, cirrus clouds typically appear white, or a light grey, in color; they form when water vapor undergoes deposition at altitudes above 5,500 m (18,000 ft), in temperate regions, and above 6,400 m (21,000 ft) in tropical ones. They also form from the outflow of tropical cyclones, and from the anvils of cumulonimbus clouds. They also arrive in advance of those storms' associated frontal systems, likely presaging a deterioration in weather conditions. Though indicating the arrival of precipitation, these clouds produce, themselves, at most fall streaks, whose ice crystals evaporate in warmer and drier air, without reaching ground level.
