Show answer & explanation
Correct answer: A
Concept
A statement-based attribute puzzle assigns qualities to named people. The dependable method is a person-by-attribute grid: enter a quality for a person wherever a statement asserts it, and treat an asserted opposite — irregular against regular — as a blocked cell. A question that demands several qualities at once is answered by the row whose every required cell is filled and none of whose cells is blocked.
Application
The four statements assert:
Namita and Samita — brilliant, studious.
Anita and Karabi — obedient, irregular.
Babita and Namita — irregular, brilliant.
Samita and Kabita — regular, obedient.
Entering only what is asserted gives this grid:
Person | Brilliant | Studious | Obedient | Regular |
|---|---|---|---|---|
Namita | Yes | Yes | — | No (irregular) |
Samita | Yes | Yes | Yes | Yes |
Anita | — | — | Yes | No (irregular) |
Karabi | — | — | Yes | No (irregular) |
Babita | Yes | — | — | No (irregular) |
Kabita | — | — | Yes | Yes |
Cross-check
Samita's row is filled across all four demanded qualities: brilliant and studious from the statement that pairs her with Namita, regular and obedient from the statement that pairs her with Kabita.
Namita carries brilliant and studious, but the statement pairing her with Babita asserts irregular, which blocks the regular requirement.
Kabita carries regular and obedient, yet no statement asserts brilliant or studious for her.
Anita carries obedient, and the statement pairing her with Karabi asserts irregular, so two of the four demanded qualities are missing for her.
Result
Samita alone is brilliant, obedient, regular and studious.
