B

Strong affinity of HCl gas for inoisture in air results in forming of droplets of liquid solution which appears like a cloudy smoke.

C

Due to strong affinity for water, concentrated hydrochloric acid pulls moisture of air towards itself. This moisture forms droplets of water and hence the cloud

D

Concentrated hydrochloric acid emits strongly smelling HCl gas all the time
