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.

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.
