Well, the correct answer is showing D. I mean is D is the correct answer? No, it is not. If u see here the answer will be C. How? This is the life cycle of a frog - First it other frogs lay eggs. Then it grows to a tadpole. Then to a froglet. And then lastly it grows into an adult frog. So, it has 4 stages. And then for cockroach, it has 3 stages which are - Eggs into a Nymph and then into an adult cockroach. So, that is why the correct answer will be C and not D.
