C Correct answer
Explanation

Deserts by definition receive less than 25 cm of annual rainfall. Hot deserts are typically located in tropical regions between 15° and 30° latitudes where descending dry air creates arid conditions. Rainfall generally decreases away from the equator towards these latitudes, not increases. Mediterranean regions experience dry summers due to shifting pressure belts, concentrating rainfall in winter.
