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