Haemozoin is a

Options

A. precursor of haemoglobin
B. toxin relased from Streptococcus infected cells
C. toxin released from Plasmodium infected cells
D. toxin relased from Haemophilus infected cells.

Explanation

**Step-by-Step Solution:**

1. **Understanding Hemozoin**: Begin by defining what hemozoin is. Hemozoin is a pigment that is produced when the malaria-causing parasite, Plasmodium, digests hemoglobin from red blood cells.

2. **Formation of Hemozoin**: Explain the process of formation. When Plasmodium feeds on the blood, it breaks down hemoglobin, and during this digestion process, hemozoin is formed as a byproduct.

3. **Function of Hemozoin**: Discuss the significance of hemozoin. It serves as a disposal product for the Plasmodium parasite, allowing it to eliminate waste from the digestion of hemoglobin.

4. **Alternative Names**: Mention that hemozoin is also referred to as malaria pigment, highlighting its association with malaria.

5. **Identifying the Correct Option**: Analyze the provided options:
- Option A: Precursor of hemoglobin - Incorrect, as hemozoin is a byproduct, not a precursor.
- Option B: Toxin released from streptococcus infected cells - Incorrect, as hemozoin is not related to streptococcus.
- Option C: Toxin released from plasmodium infected cells - Correct, as hemozoin is indeed associated with Plasmodium.
- Option D: Toxin released from haemophilus infected cells - Incorrect, as hemozoin is not produced by Haemophilus.

6. **Conclusion**: Conclude that the correct answer is option C, which states that hemozoin is a toxin released from plasmodium infected cells.

**Final Answer**: Hemozoin is a toxin released from plasmodium infected cells (Option C).
