Select the correct mirror image of the given figure when the mirror is placed…

Concept

A mirror placed on a vertical line produces a left–right reversal. Every point remains at the same height and at the same perpendicular distance from the mirror, while left and right directions are exchanged.

Application

1. Move each figure horizontally to the opposite side while keeping its vertical level: the cross goes to the upper right, the large triangular arrow to the upper left, the small triangle to the lower right, and the three-quarter circle to the lower left.

2. Reverse every horizontal direction: the large right-pointing triangle becomes left-pointing. The upward small triangle keeps its upward direction because vertical orientation does not change.

3. Mirror the three-quarter circle opening as well; its missing quadrant shifts from the lower right to the lower left.

4. Preserve all connecting segments and their relative heights after swapping left and right.

Cross-check

Tracing the horizontal order row by row gives the large triangle then the cross above, and the three-quarter circle then the small triangle below. The vertical levels remain unchanged and every horizontal direction is reversed.

Therefore, the required mirror image is the figure with the large left-pointing triangle at the upper left, the cross at the upper right, the three-quarter circle opening toward the lower left at the lower left, and the upward small triangle at the lower right.
