The life cycle of a cockroach has how many stages?

The correct answer is: 3

The correct answer is c)3.
There are only three stages in the life cycle of cockroach. The three stages are as follows: egg, nymph and adult. These usually live for 6-15 months. The female cockroach lays 10-50 eggs in a warm and humid place.
The second is the nymph stage. This is the stage when they hatch from the eggs. These have soft and white bodies. They undergo several molts and keep shedding their old shells and their body starts turning brown, tan or gray.
The last stage is the adult. After the last molt they start reproducing.
