Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Animals giving birth to young ones are called viviparous animals. The egg of these animals typically contains less of yolk insufficient to support the development of the zygote into an embryo. Hence, development proceeds inside the body of the female animal and the fully developed embryo is delivered. Oviparous animals lay an egg. Their egg typically has more amount of yolk and can support the development of the zygote into an embryo. Ovovivipary is an in-between scenario in which eggs are retained till embryo is developed and is then delivered.

So, the correct answer is option B.
