Which of the following is not an important condition for growth of coral?

A. Wave-free salt water

B. Clean salt water

C. Warm seas

D. Plenty of sunlight

Answer: Option A

Solution(By Examveda Team)

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”).
