Which graph shows a method for finding the image of point d if the parallelogram is reflected across the dashed line?

all four answers are porvided!
(the first image is the original photo not an answer)

option B

Step-by-step explanation:

Given : A parallelogram ABCD

To find : Which graph shows a method for finding the image of point D if the parallelogram is reflected across the dashed line?

Since forming the reflected image follows Every point on the image will be the same distance as its corresponding point from the pre-image.  

This distance will be perpendicular to the line of reflection i.e. dashed line  

And the second option shows the correct image .

In the second image the perpendicular was draw along the axis of reflection .

Hence the option B is correct .
