Each arrow in A changes in B without moving from its place. Do the same to every arrow in C.

In B both arrows stay where they were but point the opposite way: right becomes left, up becomes down. Reversing each arrow of C on the spot gives an arrow pointing down-left at the bottom-left, one pointing up at the top-right and one pointing right at the bottom-right: (d). (a) turns the whole figure, so the arrows also change places; (b) is a mirror image and (c) turns each arrow only a quarter turn.
