Intermediate host of malarial parasite is

Options

A. Pig
B. Man
C. Mosquito
D. Larva of mosquito

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the intermediate host of the malarial parasite. To answer this, we need to identify the organisms involved in the life cycle of the malaria-causing parasite.

2. **Identifying the Parasite**: The malarial parasite is known as Plasmodium. It is important to know that Plasmodium has a complex life cycle that involves two different hosts.

3. **Defining Host Types**: In the life cycle of Plasmodium:
- The **definitive host** is where the parasite reaches maturity and reproduces. In the case of malaria, this host is a mosquito.
- The **intermediate host** is where the parasite undergoes asexual reproduction. In this case, the intermediate host is typically a vertebrate, such as humans.

4. **Identifying the Intermediate Host**: Since the question specifically asks for the intermediate host, we need to clarify that while humans are the intermediate host for the Plasmodium species, the mosquito is the definitive host where sexual reproduction occurs.

5. **Conclusion**: Based on the definitions and understanding of the life cycle of the malaria parasite, the correct answer to the question is that the intermediate host of the malarial parasite is the mosquito.

**Final Answer**: The intermediate host of the malarial parasite is the mosquito (Option 3).
