Answer:
Option A. is the correct option.
Explanation:
As we can see in the graph attached points of ABCDEF and transformed form to the figure GHIJKL are equidistant from the y axis.
And the transformed form is not enlarged.
Therefore the ratio of ABCDEF and GHIJKL is 1 : 1.
Since the transformed form and original form both are equidistant form y axis, so y axis will be the line of symmetry for both the figures and the transformed form will be a mirror image.
Option A. is the answer.
