Detailed Solution

The above statement is false.
If the child's head appears larger in the mirror, a concave mirror should be used. A concave mirror produces an enlarged and upright mirror in this case. The middle portion of her body is unchanged, so the middle portion of the mirror must be used as a plane mirror. Her legs appear small in the mirror. In other words, the bottom section of the mirror creates a smaller image of the legs. Because the image is produced by a convex mirror, it is smaller. The erect and diminished image was clearly produced by the convex mirror.
The correct statement would be the order of combinations for the magic mirror from the top is concave, plane and convex.
