A domino tile with an orange arrow above it is placed in front of a mirror on its LEFT side. Which panel shows the mirror image?

The two halves swap sides: the three-dot diagonal moves to the right half (now rising to the right), the L of three dots moves to the left half with its corner dot on the left, and the arrow now points left: (c). (b) keeps the arrow pointing right, (d) flips the tile upside down and (a) is a half-turn.
