Correct Answer
(B) A-III, B-I, C-II, D-IV
Solution & Explanation
Answer: (B) A-III, B-I, C-II, D-IV Solution: Common cold is caused by Rhinoviruses (A-III). Haemozoin is the toxic substance released when Plasmodium (malaria parasite) ruptures RBCs (B-I). Widal test is the diagnostic test for typhoid (C-II). Allergy is triggered by allergens such as dust mites (D-IV). Why others are wrong: Pairing common cold with Plasmodium, or haemozoin with rhinoviruses, contradicts NCERT; only B links each item to its correct cause/diagnostic/trigger. NCERT Reference: NCERT Ch7, p.131, lines 17-19, 37-38; p131 line 3; p137 line 13-14: "release of a toxic substance, haemozoin"
