Hi Pooja,

 

Any line passing through the mid point of (2,0) and (0,2).....

The midpoint is (1,1).... For any line through this point (1,1) will have perpendiculars of equal length and in opposite sense. You can clearly visualise that by marking the three points on the X-Y plane.

 

So option (A).

 

Best Regards,

Ashwin (IIT Madras).
