Correct answer
Explanation
The Empty Quarter (Rub' al Khali) is the largest continuous sand desert in the world, located primarily in Saudi Arabia, covering parts of Oman, UAE, and Yemen. It's called 'empty' due to its extreme aridity and sparse population. Yemen has a small portion, but the majority is in Saudi Arabia. China and Mauritania are incorrect.
