Show answer & explanation
Correct answer: D
Interpretation and key idea: each day the five fruits are eaten by the five members, so across Tuesday–Saturday every member ends up eating each fruit exactly once.
Start from the given fixed assignments: A = Watermelon on Tuesday; D = Apple on Tuesday; D = Pineapple on Wednesday; A = Pomegranate on Thursday; B = Pomegranate on Friday; C = Grapes on Saturday; and E does not eat Pineapple on Tuesday. Also, B and E cannot eat Watermelon or Grapes on Wednesday.
Determine Wednesday: D is Pineapple on Wednesday. B and E cannot have Watermelon or Grapes on Wednesday, so the Wednesday Watermelon and Wednesday Grapes must be eaten by A and C (the remaining people). But A already has Watermelon on Tuesday, so A cannot eat Watermelon again; therefore on Wednesday C must eat Watermelon and A must eat Grapes. The remaining two Wednesday fruits (Apple and Pomegranate) then go to B and E. Since B's pomegranate is on Friday, B must take Apple on Wednesday and E must take Pomegranate on Wednesday.
Now use the pomegranate placements: A has Pomegranate on Thursday and B has Pomegranate on Friday, while E has Pomegranate on Wednesday. That means the only remaining days for Pomegranate for the remaining people are Tuesday and Saturday. D already has Apple on Tuesday, so D cannot take Pomegranate on Tuesday; D must therefore take Pomegranate on Saturday.
Finally, D's fruits across the week: Apple (Tuesday) and Pineapple (Wednesday) are already fixed, and Pomegranate is now forced to be Saturday. That leaves Grapes and Watermelon for Thursday and Friday. But using the remaining constraints and the earlier forced assignments for other people, the only consistent placement for D's Watermelon is Thursday.
Conclusion: D eats Watermelon on Thursday.
