The symmetry line is passing through points F and E. Then the correct option is B.
<h3>What is reflectional symmetry?</h3>
Consider a plane. Consider a design or shape on that plane. Now consider an axis.
If we think of that axis as a mirror, and on the opposite side of that axis create the image of the considered shape, then if the shape's image looks exactly like the shape itself, then that shape is called to have reflectional symmetry.
Then the symmetry line is passing through points F and E. Because F and E are the mid-points of AD and BC.

Step-by-step explanation: I don't have time to explain

We have that

, which means

reduces to

when

, or reduces to

when

.
So we can expand the summation as

Notice that the 10 contributes a total of 30 from the first sum, and -30 from the second sum, so those terms cancel, leaving us with
