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

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

The correct option is a - iii, b - iv, c - i, d - ii.

Let us analyze the diseases in List-I and match them with their respective causative pathogens in List-II step-by-step:

(a) Filariasis:
Filariasis (specifically lymphatic filariasis or elephantiasis) is a chronic parasitic disease caused by filarial worms. The major pathogen responsible for this disease in humans is Wuchereria bancrofti (represented as Wuchereia bancrofti in List-II). It is transmitted through the bite of infected mosquitoes. Therefore, a matches with (iii).

(b) Amoebiasis:
Amoebiasis (or amoebic dysentery) is an intestinal infection characterized by abdominal pain, cramps, and stool with excess mucous and blood clots. It is caused by the protozoan parasite Entamoeba histolytica. Therefore, b matches with (iv).

(c) Pneumonia:
Pneumonia is an infection that inflames the air sacs (alveoli) in one or both lungs, which may fill with fluid or pus. It is caused by pathogens like Streptococcus pneumoniae and Haemophilus influenzae (spelled as Heamophilus influenzae in List-II). Therefore, c matches with (i).

(d) Ringworm:
Ringworm is a common fungal skin infection characterized by dry, scaly lesions on various parts of the body such as the skin, nails, and scalp. It is caused by fungi belonging to genera like Trichophyton, Microsporum, and Epidermophyton. Therefore, d matches with (ii).

Combining all these matches:
• (a) Filariasis → (iii) Wuchereria bancrofti
• (b) Amoebiasis → (iv) Entamoeba histolytica
• (c) Pneumonia → (i) Haemophilus influenzae
• (d) Ringworm → (ii) Trichophyton

Thus, the correct match is a - iii, b - iv, c - i, d - ii.
