Answer: Option A
Solution
Answer: Option A

Wave-free salt water is not an important condition for growth of coral. Corals need saltwater to survive and require a certain balance in the ratio of salt to water. This is why corals don't live in areas where rivers drain fresh water into the ocean (“estuaries”).
