China and Mongolia contains the largest desert in Asia. Option A is correct. The Largest desert in Asia in the Gobi Desert. This desert covers 500,000 square miles. Spanning from northern China into Mongolia, the Gobi Desert receives an average of 7 inches of rainfall each year due to the fact that the Himalaya mountains block rain clouds from reaching the region.

Nowadays, the Gobi continues to grow every year, as winds carry desert sand into nearby areas and erodes the surrounding top soil.
