Concept:Viviparity is a mode of reproduction where the embryo develops inside the parent’s body and receives nourishment directly from the mother.
Explanation:In viviparous organisms, fertilised eggs are retained within the female reproductive tract.
The developing offspring obtain nutrients and oxygen from the mother through structures such as a placenta.
This internal development continues until the young are sufficiently mature to be born.
This strategy contrasts with oviparity, where embryos develop outside the mother’s body using egg yolk.
Therefore, the defining feature of viviparity is that growth and nourishment happen inside the female.
Answer:C. Offspring develop and are nourished inside the female's body
