    about the line y = x because two of the coordinates lie on the line itself and other two are mirror images of each other about the line y = x

    yes because it will rotate due same points on x-axis.

    well D won`t work because rotation by 180 would result in reflection about y axis

    No it doesn't, @harsimran_hs4 Consider rotating the line y=x 180 degrees wrt the origin, you don't get the line y = -x

    well then tell me what is the reflection of point (-3,1) about line y = x ?

    Easier to see that the reflection of the point (3,2) about the line y=x is (2,3) which is not on the parallelogram.

    (-3, -3) and (3,3) lie on the line so after reflection they will also lie on the line and remain where they were and (-3, 1) and (3, -1) interchange their position

    But if it's to be the reflection with respect to the line y=x, then the image of each and every point must still be on the parallelogram, and the image of (-3,1), which is (1,-3) is not on the parallelogram.
