Question

Trapezoid G H J K is rotated about G 90 degrees counterclockwise to form trapezoid G prime H prime J prime K prime. Trapezoid G prime H prime J prime K prime is reflected across the line of reflection m to form trapezoid G double-prime H double-prime J double-prime K double-prime.

What is the final transformation in the composition of transformations that maps pre-image GHJK to image G'H"J"K"?

a translation to the right
a reflection across line m
a 90° rotation about point G
a 180° rotation about point G
