Step-by-step explanation
The Sahara Desert is the largest hot desert in the world with an area of more than 9,400,000 km². This desert is characterized by extreme climates since in the days it reaches high temperatures on average over 40 ° C while in the early mornings it reaches temperatures below 0 ° C. Another characteristic is that the high temperatures make the environment is arid and dry, so the percentage of water in the air and the soil is low, which makes it difficult to irrigate the land. So the correct answer is A. The Sahara.
