Question

Assertion (A): A person infected with malaria suffers from chill and high fever, recurring every three or four days.
Reason (R): The parasite attacks the RBC resulting in their rupture and release of haemozoin.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true, but (R) is not the correct explanation of (A).
• C. (A) is true, but (R) is false.
• D. (A) is false, but (R) is true.

Hint:

Haemozoin is responsible for the typical fever pattern in malaria patients.

Answer 1

The Correct Option is A

Step 1: Malarial parasite Plasmodium invades red blood cells (RBCs), multiplies, and causes their rupture.
Step 2: This leads to the release of toxic substance haemozoin which causes periodic chill and fever.
Step 3: Both assertion and reason are correct and the reason explains the assertion.
