The correct option is C ovoviviparity
Aplacental viviparity is also called ovoviviparity. The female retains the eggs inside the body after fertilisation and allows the development of the embryo inside the body without providing extra nourishment to the developing embryo as the placenta is absent. These animals like some snakes and sharks give birth to their young ones.
In Oviparous animals such as reptiles and birds, fertilised eggs are covered by a calcareous shell made of calcium carbonate and are laid in a safe space. Yolk gives nourishment to the developing embryo and also protects it from injuries.
In viviparity, development of zygote takes place inside the female's body. Most mammals are viviparous and give birth to their young ones.
