Match List-I with List-II and choose the correct answer from the options given below.

List - I	List - II
(a) Filariasis	(i) Haemophilus influenzae
(b) Amoebiasis	(ii) Trichophyton
(c) Pneumonia	(iii) Wuchereria bancrofti
(d) Ringworm	(iv) Entamoeba histolytica

The correct matching between List‑I and List‑II is: a – iii, b – iv, c – i, d – ii.

Below is a step‑by‑step reasoning for each pair:

(a) Filariasis is a parasitic disease caused by the filarial worm Wuchereria bancrofti. In List‑II, this organism is labelled as (iii). Hence, a ↔ iii.

(b) Amoebiasis is an intestinal infection produced by the protozoan Entamoeba histolytica. In List‑II, this organism appears as (iv). Therefore, b ↔ iv.

(c) Pneumonia can be caused by many bacteria; one common cause is Haemophilus influenzae. In List‑II, this bacterium is represented by (i). Thus, c ↔ i.

(d) Ringworm is a superficial fungal infection caused by dermatophytes such as Trichophyton species. In List‑II, the fungus Trichophyton is labelled (ii). Consequently, d ↔ ii.

Putting all the matches together gives the complete answer: a – iii, b – iv, c – i, d – ii.
