Question

The animals in which complete embryo develops in the mother's body through placenta are

• A. Oviparous
• B. Viviparous
• C. Ovo-viviparous
• D. Herbivorous

Answer 1

The correct option is B Viviparous

• Oviparous animals are the animals that lay eggs.
• Viviparous animals give birth to the living offspring that develop within the mother's body (as in the case of most of the mammals).
• Ovo-viviparous give birth to the young ones in eggs which are hatched within the female body (as in some reptiles and fishes).
• Herbivorous animals are those that feed exclusively on vegetable food.

So, the correct answer is option B.
