Larva is not found in the life of:-

Options

A. Pheretima
B. Taeina
C. Musca
D. Rana

Answer

To determine which organism does not have a larval stage in its life cycle, we can analyze the development process of various organisms. Here’s a step-by-step solution:

1. **Understanding Larval Stages**: First, we need to understand what a larval stage is. In many organisms, especially those that undergo metamorphosis, the larval stage is a distinct phase of development that occurs after the egg stage and before reaching adulthood.

2. **Identifying Organisms**: The question likely presents several organisms, including Feratema (earthworm), which we will analyze to see if they have a larval stage.

3. **Analyzing Feratema (Earthworm)**: In the case of Feratema, which is an earthworm, the development is direct. This means that after fertilization, the eggs develop directly into young worms without passing through a larval stage. The fertilized eggs are enclosed in a cocoon, and after a few weeks, the young worm emerges.

4. **Conclusion**: Since Feratema (earthworm) does not have a larval stage in its life cycle, it is the correct answer to the question.

5. **Final Answer**: Therefore, the organism in which a larval stage is not found is Feratema (earthworm).
