The answer should be A. Out of the 4 figures only the square has 2 lines of symmetry. The other figures like the parallelogram and the F have 0 lines of symmetry. The isosceles triangle has one line of symmetry. And the parallelogram has 0 lines on symmetry. On the vertical axis, when we divide it into 2 parts. 1 part is higher at the upper side and the second one is higher at the lower side. The same happens with the horizontal axis.
