A rise or fall in the temperature will affect both corals as well as algae, thereby causing disturbances in their mutual relationship. Due to the increasing temperature, ocean undergoes acidification, as a result of which the pH level will decrease in the sea water and the marine species also will be affected.

Thus, the most appropriate answer is option (4).
