The vertices of a triangle are located at F(-4, -2), G(2, 2), and H(0, -4). A sequence of transformations to triangle FGH results in triangle F'G'H', as shown below. Which sequence of transformations to triangle FGH results in triangle F'G'H'? :

a 90° clockwise rotation about the origin, then a dilation by a scale factor of 2 with a center of dilation at the origin, a 90° counterclockwise rotation about the origin, then a dilation by a scale factor of 2 with a center of dilation at the origin, a 90° counterclockwise rotation about the origin, then a dilation by a scale factor of 1/2 with a center of dilation at the origin, a 90° clockwise rotation about the origin, then a dilation by a scale factor of 1/2 with a center of dilation at the origin
