Answer:
Option (A)
Explanation:
Desalination is usually defined as a process by which the salt components and other particles are eliminated from the saline water. It is a very expensive process.
The middle east countries are rich in terms of oil, petroleum and natural gases, but there is a large scarcity of water. So, this process is extensively carried out in the Middle East in order to purify the water and use it for drinking, agricultural and some other purposes. It produces more than 70% of desalinated water in the world.
Thus, the correct answer is option (A).
