Match List-I with List-II and select the correct answer using the codes given below the lists : List-I (Disease)
Explanation
The matching of diseases to their causative organisms is as follows: Filaria is caused by parasitic nematodes (roundworms) such as Wuchereria bancrofti, which reside in the lymphatic system. Influenza is a viral respiratory infection caused by the influenza virus [2]. Ringworm is a common fungal infection of the skin, despite its name, and is caused by dermatophytes like Trichophyton. Typhoid is an enteric fever caused by the bacterium Salmonella typhi, which typically infects the intestines . Therefore, the correct sequence for List-I (A-B-C-D) corresponding to List-II is 3 (Nematode), 4 (Virus), 2 (Fungus), and 1 (Bacteria). This aligns with the classification of pathogens where bacteria, viruses, fungi, and worms (nematodes) act as primary disease-causing agents [3].
