Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Oviparous animals are animals that lay eggs. Fertilization can be external or internal, but hatching always takes place in the external environment, never in the mother's womb. Fish, amphibians, reptiles, birds and even occasionally some mammals, are oviparous. These animals usually lay their eggs in well-protected nests, where the embryo develops inside the egg before hatching. 
So, the correct option is 'none of these'.
