In Plasmodium, diploid stage is

Options

A. Oocyst
B. Gamont
C. Schizont
D. Sporozoite.

Answer

To answer the question regarding the diploid stage in Plasmodium, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Plasmodium**: Plasmodium is a genus of parasitic protozoa known to cause malaria. It has a complex life cycle that involves both sexual and asexual reproduction and requires two hosts: humans and female Anopheles mosquitoes.

2. **Identifying the Life Cycle Stages**: In the life cycle of Plasmodium, there are several key stages:
- **Gametocytes**: These are the sexual forms of the parasite that develop in the human host.
- **Gametes**: The male and female gametes are produced from gametocytes in the mosquito.
- **Zygote**: When the male and female gametes fuse, they form a diploid zygote.

3. **Formation of the Oocyst**: The zygote undergoes a transformation and elongates to become a motile organism called an oocyst. This oocyst is the diploid stage of the Plasmodium life cycle.

4. **Conclusion**: The correct answer to the question is that the diploid stage in Plasmodium is the **oocyst**.

### Final Answer:
The diploid stage in Plasmodium is the **oocyst**.
