B. remain permanently inactive till death of the host
C. transform into active schizont
D. none of the above.

Answer

To answer the question "If gametocytes are not sucked by mosquito, they will:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Gametocytes**:
- Gametocytes are the sexual forms of the malaria parasite (Plasmodium) that develop in the human host, specifically within red blood cells (RBCs).

2. **Role of Mosquitoes**:
- Mosquitoes, particularly the Anopheles species, are the vectors that transmit malaria. When a mosquito bites an infected human, it ingests the gametocytes along with the blood.

3. **Conditions for Development**:
- Once inside the mosquito's gut, the gametocytes undergo further development. They require specific conditions, such as temperature and the right environment, to mature and reproduce.

4. **Consequences of Not Being Sucked**:
- If gametocytes are not ingested by a mosquito, they remain in the human host. Without the mosquito to facilitate their development, they cannot undergo the necessary transformation into gametes.

5. **Outcome of Inactivity**:
- In the absence of the mosquito, the gametocytes will not find the appropriate conditions for survival and reproduction. Eventually, they will degenerate and die out within the human host.

6. **Conclusion**:
- Therefore, the correct answer to the question is that if gametocytes are not sucked by mosquitoes, they will degenerate and die out.

### Final Answer:
If gametocytes are not sucked by mosquitoes, they will degenerate and die out.
