Answer

Correct option: C.

There is an exception of internal fertilization which takes place in hen.

The hen is a bird. Internal fertilization take place in hen also. But a hen does not give birth to chicks (like human beings). As fertilization take place inside the body of hen and after that it travels down the oviduct, many protective layers are formed around the embryo. The hard shell that we see in hen’s egg, is the outermost protective layer. After the hard egg shell is formed around the developing embryo, the hen finally lays the egg. The hen then sits on the eggs to provide sufficient warmth to the eggs for the development of the embryo into the chicks. The embryo takes about $3$ weeks or $21$ days to develop into a complete chick. And after the chick is completely developed, the egg shell breaks open automatically and the chick comes out of it.
