B. Gamogony
C. Sporogony
D. None of the above.

Answer

To answer the question "Which phase of Plasmodium starts in man and is completed in mosquito?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Plasmodium and Malaria**:
- Plasmodium is a genus of parasitic protozoa that causes malaria in humans. It has a complex life cycle involving both a human host and a mosquito vector.

2. **Identifying the Life Cycle Phases**:
- The life cycle of Plasmodium consists of two main phases: asexual reproduction (schizogony) in the human host and sexual reproduction (gamogony and sporogony) in the mosquito.

3. **Determining Where Each Phase Occurs**:
- In humans, Plasmodium undergoes asexual reproduction (schizogony), where the parasite multiplies in the liver and red blood cells.
- In the mosquito, Plasmodium undergoes sexual reproduction, which includes the formation of gametes (gamogony) and the development of sporozoites (sporogony).

4. **Identifying the Correct Phase**:
- The question specifically asks for the phase that starts in humans and is completed in mosquitoes. This phase is the **gamogony**, where gametes are formed in the mosquito after being transmitted from the human host.

5. **Final Answer**:
- Therefore, the correct answer is **gamogony**, which is option number 2.
