The net at the top is folded into a cube with the letters outside. Which of the cubes (a) to (d) can be made from it?

From the net, Q is opposite V, R is opposite T and S is opposite U. (a) shows S beside U and (d) shows T beside R, so both are impossible. (b) shows Q, T and S, which do meet at a corner, but in the reverse order (a mirror image). (c) is correct.
