Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Elephantiasis results in a slowly developing chronic inflammation of the blood vessels of the lower limbs. Reason (R): Filarial worms like Wuchereria bancrofti live for many years in the lymphatic vessels of the host. In the light of the above statements, choose the most appropriate answer from the
Options
- ABoth Assertion (A) and Reason (R) are correct and Reason (R) is the correct explanation of Assertion (A).
- BBoth Assertion (A) and Reason (R) are correct but Reason (R) is not the correct explanation of Assertion (A).
- CAssertion (A) is correct but Reason (R) is not correct.
- DAssertion (A) is not correct but Reason (R) is correct.
Correct answer
D. Assertion (A) is not correct but Reason (R) is correct.
Step-by-step solution
Assertion (A) is not correct because elephantiasis (filariasis) results in a slowly developing chronic inflammation of the lymphatic vessels of the lower limbs, not the blood vessels. Reason (R) is correct because filarial worms like Wuchereria bancrofti and Wuchereria malayi live for many years in the lymphatic vessels of the human host, which is the underlying cause of the disease. Therefore, Assertion (A) is not correct but Reason (R) is correct. Answer: Assertion (A) is not correct but Reason (R) is correct.
