Question

Which of the following stages is necessary in the life cycle of an animal in which complete metamorphosis occurs?

• A. Adult
• B. Egg
• C. Larva
• D. All of the above

Answer 1

The correct option is D All of the above

Metamorphosis is the process by which an organism undergoes various physical changes and transforms from an immature adult or larval form into a mature adult. Complete metamorphosis includes hatching of the egg, development of larva, and finally its transformation into an adult through various physical changes.

The figure shows the metamorphosis of an insect. The life cycle of an insect includes an egg, larva, pupa, and adult stages.

Hence, egg, larva, and adult are necessary stages in the life cycle of an animal in which complete metamorphosis occurs.

So, the correct answer is option D.
