• Oviparous organisms produce their offsprings by laying eggs. Their Egg contains an embryo.
• While viviparous organisms produce offspring by giving birth to young ones. They do not lay eggs.

Crow is oviparous. Cat is viviparous. Frog is oviparous. Lizard is oviparous. Dog and cow both are viviparous. Crow and frog both are oviparous.

So the correct option is Crow, Cat.

The correct option is A.

Oviparous animals can reproduce by laying eggs. This is how most fish, amphibians, reptiles, insects, and arachnids reproduce. All birds and monotremes also reproduce like this. But, viviparous animals are born as the live young individuals.

So the correct answer is oviparous.

The correct option is B.

Animals that gives birth to their young ones are called Viviparous.

In the viviparous type of animals, females can give birth to young ones. Mammals (except egg-laying mammals), like whale, shark, mouse, humans are examples of viviparous animals. Frog is an oviparous animal. The butterfly is an oviparous animal

So, the correct answer is Human being.

The correct option is A.

• 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.

Ovipary is the development of foetus outside the mother's womb. Example, egg-laying birds.

Oviparous animals are animals that lay eggs, with little or no other embryonic development within the mother. Hen and frogs, they both lay eggs and hence are oviparous.
On the other hand, viviparous are those that give birth to live young ones and in ovoviviparous, there is internal fertilization and young are born live but there is no placental connection and young ones are nourished by yolk egg.
So, the correct answer is option A.

Viviparous animals are those animals which give birth to young ones. Birth of fully developed young ones is attributed to the presence of a highly developed placenta which helps the embryo to develop fully in mother's womb. 
So, the correct option is 'Viviparous'.

• Birds are oviparous meaning they lay eggs. On the other hand, dogs do not lay eggs and are viviparous meaning dogs give birth to live young ones. So, bird's eggs are available in markets.
