The correct sequence of stages in complete metamorphosis is Egg, Larva, Pupa, Adult. This process is characteristic of certain insects and includes four distinct stages.

It begins with the egg stage, where the fertilized egg is laid by the adult female. Following hatching, the organism enters the larval stage, which is often characterized by rapid growth and feeding. In this stage, the larva undergoes several molts, leading to continuous growth until it is ready to transition into the next phase.

The pupa stage follows, during which the organism transforms within a protective casing. This is a pivotal stage where the larva undergoes a significant transformation, restructuring its body to become an adult. Finally, the adult emerges, ready to reproduce and continue the life cycle.

Understanding this progression is crucial, especially in fields like pest control and agriculture, where knowledge of insect life cycles can influence management strategies.
