The correct answer is - 2. The Gobi Desert.
The Gobi Desert is a physical feature that is located in both Mongolia and China. The desert is located in the central northern part of China, in the region known as Inner Mongolia, and in the southern part of Mongolia.
This desert is one of the biggest deserts in the world. It is also the northernmost desert in the world, and the coldest one during the winter, with temperatures going 20,30, even 40 C degrees bellow zero, while in the summer they reach up to 35 C degrees.
Unlike the stereotypical desert with sand dunes, and very tiny particles of sand dominating the landscape, the Gobi desert is not like that. This desert is dominated by rocks from all sizes and shapes, so it makes up for one vast dry and rocky landscape.
