Final answer:
The stages in the complex life cycle of an insect include egg, larva, pupa, and adult, which all look different from one another. The entire process, known as metamorphosis, involves the remarkable transformation of the insect from one stage to the next. Thus, all the listed options E) (Egg, Larva, Pupa, Adult) are correct.
Step-by-step explanation:
Each stage in the complete life cycle of an insect, namely egg, larva, pupa, and adult, looks different from the others. The life cycle begins with the insect as an egg. After the egg hatches, the insect transitions into a larva, which eats and grows until it enters the pupa stage. At this stage, the insect is usually immobile and may be encased in a cocoon. Inside the pupa, an incredible transformation known as metamorphosis occurs. Here, the tissues and appendages of the larva reorganize into the adult form. As a result, larvae and adults often have completely different forms and behaviors, which allows them to occupy different habitats and reduce competition for food. Indicating that egg, larva, pupa, and adult are all stages that occur in the complex life cycle of an insect.
