Concept:Each disease is caused by a specific pathogen belonging to one of four groups: bacteria, viruses, fungi, or protozoa.
Explanation:Malaria is caused by
Plasmodium, which is a protozoan, so
(a) matches with
(iii) under Protozoa.
Tuberculosis is caused by
Mycobacterium tuberculosis, which is a bacterium, so
(b) matches with
(ii) under Bacteria.
Hepatitis is caused by the hepatitis virus, so
(c) matches with
(iv) under Virus.
Ringworm is a skin infection caused by fungi, so
(d) matches with
(i) under Fungi.
Thus, the correct matching is exactly
(a)→(iii),
(b)→(ii),
(c)→(iv),
(d)→(i), which corresponds to Option B.
Answer:Option B:
(A)−(iii),
(B)−(ii),
(C)−(iv),
(D)−(i).
