Identify the transformation that carries the figure onto itself.
a) rotate 90° clockwise about (8, −6) and reflect across the line y = 6
b) rotate 270° clockwise about (8, −6) and reflect across the line x = 8
c) rotate 270° clockwise about (8, −6) and reflect across the line y = 6
d) rotate 360° clockwise about (8, −6) and reflect across the line x = 8
