Question

Accepted Answer

Correct Option: (d) Oranges To find the cause of the sickness, we analyze the consumption of fruits by the four individuals. A ate: Grapes, Pineapple (Healthy) B ate: Grapes, Oranges (SICK) C ate: Oranges, Pineapple, Apple (SICK) D ate: Grapes, Apple, Pineapple (Healthy) We look for the fruit eaten by both B and C (who fell sick) that was not eaten by A and D (who remained healthy). Comparing B and C, the only common fruit they both consumed is Oranges. Now let us verify against the healthy individuals: A did not eat Oranges, and D did not eat Oranges. Grapes was eaten by B (sick) but also by A and D (healthy), so grapes did not cause sickness. Pineapple was eaten by C (sick) but also by A and D (healthy), so pineapple did not cause sickness. Apple was eaten by C (sick) but also by D (healthy), so apple did not cause sickness. Therefore, the consumption of Oranges is the sole common factor unique to the sick individuals B and C. This logically establishes Oranges as the cause of sickness. Hence, option (d) is correct.
