Darsh Jain is right, the line is a part of the figure, not just a line of symmetry. Hence answer is 2 and correct option is D) None of these.
I agree to harsh I think that correct answer is B. Who are telling that correct answer is D can just elaborate the answer.
The answer is 2 OR option D because the horizontal line in the center of the figure is a part of the figure not the line if symmetry. Please look clearly .
Yes , Darsh is right. The horizontal line is a part of the figure , even though most of us may interpret it as a line of symmetry .
