Which is the vector for malaria ?

Options

A. Male culex
B. female culex
C. Female Anopheles
D. aedes

Answer

### Step-by-Step Solution:

1. **Understanding Malaria**: Malaria is a disease caused by a parasite known as Plasmodium, which is transmitted through the bite of infected mosquitoes.

2. **Identifying the Vector**: The term "vector" refers to an organism that transmits a disease-causing pathogen. In the case of malaria, the vector is a specific type of mosquito.

3. **Types of Mosquitoes**: There are several types of mosquitoes, but not all of them are vectors for malaria. The most common types mentioned are:
- Male Culex
- Female Culex
- Female Anopheles
- Aedes mosquitoes

4. **Focusing on Female Anopheles**: Among these, the female Anopheles mosquito is identified as the primary vector for malaria. This is because it is the female mosquitoes that carry the Plasmodium parasite.

5. **Reason for Female Anopheles as Vector**: The female Anopheles mosquito secretes a special protein that allows the Plasmodium to thrive and be transmitted to humans. Male mosquitoes do not carry this protein, hence they do not transmit malaria.

6. **Conclusion**: Therefore, the correct answer to the question "Which is the vector for malaria?" is the **female Anopheles mosquito**.
