The correct option is C Whale
Young one of whale is known as calf. Feeding by the calf is different to that of land mammals. Because the mammary glands lie within the mother’s genital slit, the baby doesn’t actually latch on to a nipple. Instead strong muscles squirt the milk into the calf’s mouth. Whale milk is very concentrated with fat and protein and this enables the calf to grow very rapidly. Hence, option C is correct.
