| List-I (Diseases) | List-II (Pathogen) |
| (A) Pneumonia | (I) Wuchereria bancrofti |
| (B) Typhoid | (II) Microsporum |
| (C) Ringworm | (III) Salmonella |
| (D) Elephantiasis | (IV) Haemophilus influenzae |
Accurate matching of List-I (Diseases) to List-II (Pathogens) requires identifying the pathogen responsible for each disease.
Consequently, the correct pairings are (A)-(IV), (B)-(III), (C)-(II), and (D)-(I).
