It should be D because AB does not show the mirror of the other side but if you tilt it a little bit you can see GH makes the mirror half of the image.

Calm down. To understand this, you need to know the definition of 'symmetryical line', which is the line that divides a figure into a mirror image, and if you place a mirror along the line of symmetry, it should show the other side correctly, a reflection of the other side. AB doesn't divide this figure into a mirror image of each half, but it you tilt it along GH, it shows a mirror image. Concentration is all that was needed.
