Solution
The correct option is C Desert In desert biome, vegetation is scarce and soil is sandy. The soil is exposed to the atmosphere because plant cover is missing. During day time sand becomes hot on exposure to sun rays and during night, after sunset, sand rapidly cools and loses heat fast. Hence, the diurnal temperature of soil surface varies most in deserts. This is one of the reasons for poor vegetation and faunal population in deserts.
