Which rule describes the composition of transformations that maps figure ABCDE to figure A"B"C'D"E"?

In the given figure ABCDE is transformed to figure A”B”C”D”E.When a figure is reflected along a line  the reflected image is at the same distance to the line as the original figure was.The figure ABCDE is first reflected through the line m to get the figure A'B'C'D'E'. When a figure is rotated by 180 degrees the x and y coordinates change its place and y sign is reversed.A'B'C'D'E' IS  rotated by 180 degrees to come to figure A"B"C"D"E".Among all the options give the last option that is   r m 0 Rc180°   is the right answer.
