Question

The following question consists of two statements – assertion (a) and reason (r). Answer selecting the appropriate option:
(a) : Typhoid is caused by staphylococcus bacteria.
(r) : The mode of spread of this infection is through the fecal-oral route.

• A. Both (a) and (r) are true and (r) is the correct explanation of (a).
• B. Both (a) and (r) are true and (r) is not correct explanation of (a).
• C. (a) is true, but (r) is false.
• D. (a) is false, but (r) is true.

Hint:

Typhoid prevention relies on good sanitation, safe drinking water, and proper hand hygiene.

Answer 1

The Correct Option is D

The correct answer is (D): The assertion (a) is false while the reason (r) is true. Typhoid fever is caused by the bacterium Salmonella typhi, not Staphylococcus. However, the reason statement is correct — typhoid spreads primarily through the fecal-oral route, which means infection occurs when food or water contaminated with feces containing the bacteria is ingested. Poor sanitation and hygiene contribute to the transmission of typhoid.
