Identify the statement(s) that is/are true regarding oviparous animals.

• B. They lay fertilized eggs
• C. They give birth to young ones
• D. They lay unfertilized eggs

Answer 1

Answer: (B), (D)

They lay unfertilized eggs

Egg-laying animals are termed as oviparous animals. Fishes and frogs lay unfertilized eggs whereas reptiles and birds lay fertilized eggs. Regardless, in both cases they are called oviparous animals. In fishes and frogs, fertilisation and embryo development occurs outside the body whereas in animals like reptiles and birds, fertilisation occurs inside the body.
