The correct option is B.
The area described in the question given above is desert.

Most deserts are found within the latitude 30 degree north and latitude  30 degree south. Some deserts can also be found around mountain. The temperate range in desert is quite wide. During the day, the temperature may be as high as 50 degree Celsius and the temperature may drop below zero degree Celsius in the night. Thus, it is always very cold at night compares to during the day.
