A cube , on whose side letters have been written, is shown below in different positions as can be seen from different directions. Find the missing letter.

Logic: In these types of dice problems, we should write all three numbers/letters in clockwise or anticlockwise from a fix common number/letter.

From 1st and 3rd dice rotate clockwise from D.

D ⟷ U

So, Y is missing according to the above figure.

Thus, the correct answer is (d).
