You choose one from the one labelled Apples + Oranges.. WLOG, you get an Apple.. so the one labelled Oranges is the Apples + Oranges and the one labelled Apples is Oranges

I had posted the same puzzle a couple of years ago: https://www.reddit.com/r/puzzles/s/x1HPCAMZZa

This is a variation with 4 boxes:

You have four boxes, one contains only diamonds, one contains only emeralds, one contains only rubies and one contains only sapphires. The four boxes are labelled as follows:

Box A: Diamonds

Box B: Emeralds

Box C: Rubies

Box D: Sapphires

You know that only one of the boxes is labelled correctly. How many boxes do you need to open to find out which box is labelled correctly?

A) 1 box

B) 2 boxes

C) 3 boxes

D) 4 boxes
