Segment XY is transformed using rigid transformation to get segment X′Y′ as shown in the graph. Segment X Y with endpoints X (1,6), Y (5, 0), & segment X prime Y prime with endpoints X prime (0, negative 6), Y prime (negative 4, 0).

Which series of transformations correctly maps XY¯¯¯¯¯¯¯¯ to X′Y′¯¯¯¯¯¯¯¯¯¯¯¯?

a rotation 180∘ clockwise about the origin and a translation right 1 unit
a rotation 180∘ clockwise about the origin and a translation left 1 unit
a reflection across the y-axis and a rotation 90∘ clockwise about the origin
