Options

A. Stomach of female Anopheles
B. Stomach of male Anopheles
C. Blood of man
D. Salivary glands of Anopheless

Answer

To answer the question "Gametocytes of malarial parasite are found in," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Life Cycle of the Malarial Parasite**:
- The malarial parasite, primarily *Plasmodium*, has a complex life cycle that involves two hosts: humans and female Anopheles mosquitoes.

2. **Identifying the Hosts**:
- In humans, the parasite goes through several stages, including the liver stage and the blood stage. In the mosquito, the sexual reproduction occurs.

3. **Focus on Gametocytes**:
- Gametocytes are the sexual forms of the malaria parasite. They are produced in the human host and are essential for the transmission of malaria to mosquitoes.

4. **Location of Gametocytes**:
- In humans, after the merozoites infect red blood cells (RBCs), they can develop into immature gametocytes. These gametocytes are found circulating in the blood of the infected human.

5. **Transmission to Mosquito**:
- When a female Anopheles mosquito bites an infected human, it ingests the gametocytes along with the blood. Inside the mosquito, these gametocytes will develop into gametes and eventually form a zygote.

6. **Conclusion**:
- Therefore, the correct answer to the question is that the gametocytes of the malarial parasite are found in the blood of humans.

### Final Answer:
The gametocytes of the malarial parasite are found in the **blood of man** (Option 3).
