B. The gametocytes develop in RBC
C. Female mosquito takes up sporozoites with blood meal
D. When mosquito bites a man, gametocytes are injected.

Answer

To identify the correct statements about the life cycle of Plasmodium, we can analyze each statement provided:

1. **Statement 1**: "Parasites reproduce sexually in liver cells."
- This statement is **incorrect**. Plasmodium parasites reproduce asexually in the liver cells. The sexual reproduction occurs in the mosquito.

2. **Statement 2**: "The gametocytes develop in RBC."
- This statement is **correct**. Plasmodium infects red blood cells (RBCs) and develops into gametocytes within them.

3. **Statement 3**: "Female mosquito takes up sporozoites with blood."
- This statement is **incorrect**. When a female mosquito feeds on blood, it takes up gametocytes, not sporozoites. The sporozoites are injected into the human host during the mosquito's bite.

4. **Statement 4**: "When mosquitoes bite a man, gametocytes are injected."
- This statement is **incorrect**. During the bite, the mosquito injects sporozoites into the human host, not gametocytes.

**Conclusion**: The only correct statement is that "the gametocytes develop in RBC."
