The correct answer is D because Butterfly goes through the Four stages of Life Cycle . First butterfly give eggs , then the eggs broke and Larva or Catterpillar comes out , then it becomes Pupa and then at last it emerges as a another Butterfly . Frog is also an example of four stage life Cycle .

Thank You

Butterflies

Butterflies undergo a four-stage life cycle known as complete metamorphosis. This means that they go through distinct stages of growth and development, each with its own unique characteristics.

Egg Stage:
The life cycle of a butterfly begins when a female butterfly lays eggs. These eggs are usually laid on leaves or stems of plants that will serve as food for the caterpillars once they hatch. The eggs are usually small and come in various shapes and colors, depending on the species of butterfly.

Larva Stage (Caterpillar):
Once the eggs hatch, the larvae emerge. These larvae are commonly known as caterpillars. Caterpillars are voracious eaters and spend most of their time feeding on plants. They have a soft body and a distinct head, with six true legs and several pairs of fleshy prolegs. During this stage, the caterpillar goes through several molts, shedding its skin as it grows. The caterpillar also stores energy in the form of fat reserves for the next stage of its life cycle.

Pupa Stage (Chrysalis):
After the larval stage, the caterpillar enters the pupa stage. This is a transformative stage during which the caterpillar undergoes a remarkable change. It forms a protective covering around itself called a chrysalis. Inside the chrysalis, the caterpillar's body breaks down and rearranges itself into a butterfly. This process is known as metamorphosis and can take anywhere from a few days to several weeks, depending on the species.

Adult Stage:
Finally, the adult butterfly emerges from the chrysalis. Its wings are initially soft and crumpled, but they gradually expand and harden. The adult butterfly, also known as an imago, is the reproductive stage of the life cycle. Its main purpose is to find a mate, reproduce, and continue the life cycle by laying eggs.

By going through these four stages of egg, larva (caterpillar), pupa (chrysalis), and adult, butterflies undergo a complete metamorphosis and demonstrate a four-stage life cycle.
