Solution

The correct option is B Viviparous
The egg of birds and reptiles is rich in yolk and supports full development of embryo. They lay eggs and are called oviparous animals. Human egg is not rich in yolk and cannot support development of embryo. Hence, the development of embryo occurs inside the body of female parent. Humans are thus viviparous animals giving birth to young ones.
The process of development of embryo from an unfertilized egg is known as parthenogenesis. It occurs in bees, aphids, water fleas etc.
Ovo vivipary is the phenomenon when an embryo develops inside egg and remains in the body of mother until hatching.
So, the correct answer is 'Viviparous'
