Fertilization and development of malarial parasite takes place in:

Options

A. RBC of human
B. Liver of human
C. Gut of mosquito
D. Salivary gland of mosquito

Answer

**Step-by-Step Solution:**

1. **Understanding the Malarial Parasite**: The malarial parasite is known as Plasmodium, which is responsible for causing malaria in humans.

2. **Life Cycle of Plasmodium**: Plasmodium has a complex life cycle that involves two hosts: a primary host and a secondary host. This life cycle is termed diagenetic.

3. **Identifying the Hosts**:
- **Primary Host**: The primary host for Plasmodium is the female Anopheles mosquito. In this host, Plasmodium undergoes sexual reproduction.
- **Secondary Host**: The secondary host is humans, where asexual reproduction occurs.

4. **Fertilization and Development**: In the female Anopheles mosquito, fertilization occurs in the gut (or the elementary canal) of the mosquito. The male and female gametes fuse to form a zygote, which then develops further in the mosquito's gut.

5. **Conclusion**: Therefore, the correct answer to the question is that fertilization and development of the malarial parasite take place in the gut of the female Anopheles mosquito.

**Final Answer**: The gut of the female Anopheles mosquito.
