Assertion : In malaria, a person experiences chills and high fever recurring every three to four days.
Reason : This is caused by the release of haemozoin with rupture of liver cells.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step 1: Understand the Assertion
The assertion states that in malaria, a person experiences chills and high fever recurring every three to four days. This is a well-documented symptom of malaria caused by the Plasmodium parasite.

### Step 2: Analyze the Reason
The reason given is that this fever is caused by the release of hemozoin with the rupture of liver cells. However, this statement is incorrect because the chills and fever in malaria are actually caused by the rupture of red blood cells (RBCs), not liver cells.

### Step 3: Connect the Assertion and Reason
While the assertion is true (malaria does cause chills and fever every few days), the reason provided is false because it incorrectly identifies the source of hemozoin release. Hemozoin is released when the Plasmodium parasite ruptures the RBCs after multiplying in the liver, not from the liver cells themselves.

### Step 4: Conclusion
Based on the analysis:
- The assertion is true.
- The reason is false.

Thus, the correct answer is that the assertion is true but the reason is false.

### Final Answer
The assertion is true, but the reason is false.
