C Correct answer
Explanation

Whales are mammals that live in the ocean. They breathe air, give birth to live young, and nurse their offspring with milk - all mammalian characteristics. However, the question states 'only mammal' which is incorrect since dolphins, porpoises, seals, and other marine mammals also exist.
