Solution

The correct option is B A saturated solution of ammonia in water
${N H}_{3}$ is highly soluble in water.
Solution of ammonia in water is called liquor ammonia.
Liquor ammonia is highly volatile in nature and has a high latent heat of evaporation.
Hence, it will lose weight when exposed to atmosphere.
