Answer:
The correct answer is (C).
Step-by-step explanation:
The Arabian Gulf is the region of the world that has the majority of sea water desalination facilities. This is because the Arabian Gulf is a very water-scarce region, and desalination is a way to provide fresh water for drinking and irrigation. There are over 1,000 desalination plants in the Arabian Gulf, and they produce over 10 billion cubic meters of fresh water per year.
China is the second-largest producer of fresh water from desalination, with over 200 desalination plants. Europe is the third-largest producer, with over 100 desalination plants. The United States has a relatively small number of desalination plants, with only about 20 plants in operation.
