C Correct answer
Explanation

Elephants are the only mammals that lack a pleural space - the fluid-filled gap between the lungs and chest wall found in other mammals. Their lungs are directly attached to the chest wall and diaphragm by connective tissue, which may help them withstand the pressure changes of snorkeling and using their trunks in water.
