Three boxes are labeled: Box A ('Apples'), Box B ('Bananas'), Box C ('Apples and Bananas'). You are told that all three labels are completely incorrect. By reaching into just one box and pulling out a single piece of fruit, which box must you open to figure out the correct contents of all three boxes?
Box C
Box C's label is wrong, so it cannot contain both apples and bananas; it must contain solely apples or solely bananas. Drawing one fruit from Box C reveals its exact contents. Because all labels are wrong and unique, knowing Box C allows you to deduce the rest.
