The correct answer is option D. produces an adult that's completely different from the larva.
In the incomplete metamorphosis there are three stages, egg, nymph and larva. The nymph hatch from egg, and look similar to the adult.
Unlike this, in complete metamorphosis, there are 4 stages, egg, larva, pupa and adult. In this case, the larva is completely different from the adult. For example, the butterfly larva, which is a caterpillar is completely different from adult butter fly.
