The correct answers are:
B. covers almost the entire Arabian Peninsula;
D. has very few people living there;
The Arabian desert is one of the biggest deserts in the world. It is also one of the hottest and driest places on the planet. This desert occupies almost all of the Arabian Peninsula, with only parts of the coastline and the mountains along the southern half of the coastline of the peninsula, not being part of it.
In one way or another, most of the desert have some water bodies in them, be it a river or a lake. The Arabian Desert actually doesn't have a single river in it despite its vastness. Because of the harshness of the desert, there's very few people living in it, with almost all of the population on the peninsula being located along the coastline.
