Correct Answer
(D) -(iii), (b)-(iv), (c)-(i), (d)-(ii)
Solution & Explanation
Answer: (D) (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii) Solution: Typhoid (a) is caused by Salmonella (iii); Pneumonia (b) by Haemophilus (iv) (Haemophilus influenzae); Filariasis (c) by Wucheria (i) (Wuchereria); Malaria (d) by Plasmodium (ii). This gives a-iii, b-iv, c-i, d-ii. Why others are wrong: The other options mispair the bacterial, helminth and protozoan agents (e.g., assigning Plasmodium to typhoid or Haemophilus to malaria).
