A dice has its faces marked by letters C, L, O, U, R and F. Two positions of the same dice are shown in the given figures. Which face is opposite to face L?

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

Common face to clock wise rotate:

So,  R is opposite face of L.

Thus, the correct option is: (d) R
