Study the $3\times 3$ tile: a violet square, two half-shaded corners, a dot and an orange arrow. Which panel shows the tile in the dashed mirror?

Columns 1 and 3 swap and column 2 stays: the violet square moves to the middle-right, the yellow half-square to the top-left corner with its right angle top-LEFT, the blue half-square stays in the bottom middle but its right angle moves to the top-right, the dot goes bottom-left and the arrow now points RIGHT: (c). (b) leaves the arrow pointing left, (a) swaps top and bottom and (d) does both.
