What is the result of larvae in complete metamorphosis?

In the process of complete metamorphosis, the life cycle of certain insects includes distinct stages: egg, larva, pupa, and adult. After hatching from the egg, the larvae typically exhibit significant growth and feeding behaviors but do not resemble the adult form. Following the larval stage, these insects enter the pupa stage, during which they undergo a remarkable transformation. During pupation, the insect’s body is reorganized, leading to the eventual emergence of the adult form, which is usually very different in appearance and behaviour from the larva. This intermediate pupa stage is crucial for the development of the structures and functions necessary for adult life, such as wings and reproductive organs.

While the other options present ideas that do not align with the concept of complete metamorphosis, the presence of the pupa stage is the defining characteristic that separates this type of metamorphosis from incomplete metamorphosis, where insects develop gradually without a distinct pupal phase.
