II. Plasmodium vivax malaria is the most serious one and can be fatal .
III. Plasmodium enters the female body by the bite of the female Anopheles mosquito.

Options

A. I-True , II - False , III - True , IV - False
B. I-True , II - True , III - False , IV - False
C. I- False , II - True , III - True , IV - True
D. I- False , II - False , III - False , IV - True

Answer

To solve the question, we need to evaluate each statement about malaria and the Plasmodium parasite to determine which are true and which are false.

### Step-by-Step Solution:

1. **Evaluate Statement I:**
- **Statement:** Malaria is caused by a protozoan known as Plasmodium.
- **Analysis:** This statement is true. Malaria is indeed caused by the Plasmodium genus of protozoan parasites.
- **Conclusion:** True.

2. **Evaluate Statement II:**
- **Statement:** Plasmodium vivax malaria is the most serious one and can be fatal.
- **Analysis:** This statement is false. The most serious and potentially fatal form of malaria is caused by Plasmodium falciparum, not Plasmodium vivax.
- **Conclusion:** False.

3. **Evaluate Statement III:**
- **Statement:** Plasmodium enters the female body by the bite of the female Anopheles mosquito.
- **Analysis:** This statement is true. The female Anopheles mosquito is the vector that transmits the Plasmodium parasite to humans through its bite.
- **Conclusion:** True.

4. **Evaluate Statement IV:**
- **Statement:** The parasites initially attack the liver cells and then multiply in the WBCs causing their rupture.
- **Analysis:** This statement is false. While it is true that Plasmodium initially attacks liver cells, it multiplies in red blood cells (RBCs), not white blood cells (WBCs). The rupture refers to RBCs, which leads to the symptoms of malaria.
- **Conclusion:** False.

### Summary of Results:
- Statement I: True
- Statement II: False
- Statement III: True
- Statement IV: False

### Final Answer:
The true statements are I and III; the false statements are II and IV.
