The chart is ordered from left to right, and the code "⁴⁰K" appears twice, so we can assume that it is the key code that needs to be placed in the middle of the chart. Both codes to the left and right of it have different letters in the last position, so they cannot be adjacent to it. Only code D, with the same letter in the last position, can be adjacent to it, making the correct order: C-D-B-A-E.
