Sol.(c) [Key Concept: Viviparity — More Evolved (Young Protected Internally)] Viviparity is considered more evolved because inside the mother's body, the young ones are protected and cared for after birth, leading to more chances of survival (e.g., mammals). In oviparity, the female lays fertilised eggs covered by a hard calcareous shell in the environment — the young are left on their own with fewer survival chances.
