To qualify as a desert, a region must a. be hot, with a mean annual temperature greater than 25°c (77°f) b. be arid, with less than 15% of the ground surface vegetated c. have a mean annual temperature greater than 25°c and less than 5 cm annual rainfall d. have no rainfall three out of four seasons

Option B

Explanation:

Deserts are described as the regions where the region receives the rainfall on an average is less than 10 inches in a year. In order to define the desert in a more appropriate basis it is defined on the basis of its aridity.The desert region are characterized by lower than 15 % area of the ground surface being covered with vegetation. Lower vegetation, fewer clouds, low level of humidity and fewer water bodies in these areas are the characteristics of these regions the absorption and radiation of the sun's rays from the surface is maximum resulting in extreme temperatures both during the days and seasons.
