The two options that are symmetrical are shown below with their symmetry.
What is reflectional symmetry?
The symmetry with regard to a reflection is known as reflection symmetry, line symmetry, mirror symmetry, or mirror-image symmetry. That is, a figure with reflectional symmetry does not alter when it is reflected. There is a line/axis of symmetry in 2D.
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.
From the given figure, the polygon that is symmetrical are the ones that are in the top two. Hence, the two options that are symmetrical are shown below with their symmetry.
