Choose the correct mirror image from the alternatives of the given figure:

Concept: A mirror (lateral / left–right) image is the figure you would see reflected in a vertical mirror placed to one side. Reflection reverses only the left–right axis: every element on the left moves to the matching place on the right and every element on the right moves to the left. Top stays top and bottom stays bottom — vertical positions and the up/down orientation of an arrow are NOT changed, and nothing is rotated.

Application to this figure:

1. List the asymmetric (side-distinguishable) parts of the original: the upward arrow with its short cross-bar sits on the left edge; a plain vertical support sits on the right edge; inside the triangle the star-shaped gear is on the left and the circular dial is on the right.

2. Reflect each one across a vertical centre line: the arrow with its cross-bar must move to the right edge, the plain support must move to the left edge, the star must move to the right and the circular dial must move to the left.

3. Keep what reflection does NOT change: the arrow still points up, every part stays at the same height, and no piece is turned upside-down or rotated.

Result: The figure that satisfies all of this shows the upward arrow on the right, the plain support on the left, the circular dial on the left inside the triangle and the star-shaped gear on the right — that is the correct mirror image.

Cross-check: Mentally fold the chosen figure back over the same vertical line; it should land exactly on the original, with the star and dial returning to their starting sides and the arrow back on the left. A figure that needs only a left–right fold (never a top–bottom fold or a turn) to recover the original is the true mirror image.
