One of the lines that carries the regular polygon onto itself is a line that is a perpendicular bisector of line segment AB.
A shape that maps onto itself after reflection has reflectional symmetry.
This means that, for polygon ABCDEFG to map onto itself after reflection, the line of reflection must divide the polygon into equal halves.
The perpendicular bisector of line segment AB is one of those lines, because it divides the polygon into equal halves at point E and line segment AB
Hence, the true option is (D)
