It is B since GH is not perpendicular by the smallest of angles. EF is perpendicular since if you look at the triangles or 5-sided shapes that are made when lines AB and EF come through a square with an angle not equal to 45 degrees, the sizes are the same. This shows that AB and EF are a pair of perpendicular lines.
