Question

Match the following human diseases in Column-I with their causal organism in Column-II

• A. P - 3 ; Q - 1 ; R - 4 ; S - 5
• B. P - 1 ; Q - 2 ; R - 3 ; S - 4
• C. P - 2 ; Q - 4 ; R - 1 ; S - 3
• D. P - 2 ; Q - 1 ; R - 4 ; S - 3

Hint:

When studying parasitic diseases, remember that {Trypanosoma brucei} causes sleeping sickness, {Trypanosoma cruzi} causes Chagas disease, {Wuchereria bancrofti} causes elephantiasis, and {Borrelia burgdorferi} causes Lyme disease.

Answer 1

The Correct Option is D

The correct matching between the diseases and their causal organisms is as follows:

- Sleeping sickness (P) is caused by Trypanosoma brucei, a protozoan parasite transmitted by tsetse flies. Therefore, P matches with 2 (Trypanosoma brucei).

- Chagas disease (Q) is caused by Trypanosoma cruzi, a protozoan parasite transmitted by triatomine bugs. Therefore, Q matches with 1 (Trypanosoma cruzi).

- Elephantiasis (R) is caused by Wuchereria bancrofti, a parasitic roundworm transmitted by mosquitoes. Therefore, R matches with 4 (Wuchereria bancrofti).

- Lyme disease (S) is caused by Borrelia burgdorferi, a bacteria transmitted by ticks. Therefore, S matches with 3 (Borrelia burgdorferi).

Thus, the correct answer is option (D).
