Comma-shaped stage in the life cycle of Mosquito is

Options

A. Larval stage
B. Pupal stage
C. Imago stage
D. None of the above.

Answer

To answer the question about the comma-shaped stage in the life cycle of a mosquito, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Life Cycle of a Mosquito**: The life cycle of a mosquito consists of four main stages: egg, larva, pupa, and adult (imago).

2. **Identify the Stages**:
- **Egg Stage**: This is the initial stage where the female mosquito lays eggs.
- **Larval Stage**: After hatching, the mosquito enters the larval stage, which is aquatic and involves several molts (instars).
- **Pupal Stage**: Following the larval stage, the mosquito transforms into a pupa.
- **Adult Stage (Imago)**: Finally, the pupa metamorphoses into an adult mosquito.

3. **Focus on the Pupal Stage**: The question specifically asks for the comma-shaped stage. The pupa is known to be active and has a distinct comma shape during this stage.

4. **Evaluate the Options**:
- **Larval Stage**: Incorrect, as it does not have a comma shape.
- **Pupal Stage**: Correct, as it is the stage that is comma-shaped.
- **Imago Stage**: Incorrect, as this is the adult stage and does not resemble a comma.
- **None of the Above**: Incorrect, since the correct answer is present.

5. **Conclusion**: The comma-shaped stage in the life cycle of a mosquito is the **pupal stage**.

### Final Answer:
The correct answer is **B) Pupal Stage**.
