A triangle with vertices A(0,2), B(-3,2), and C(-3,0) is reflected about the x axis; then the image \triangle A^{\prime} B^{\prime} C^{\prime} is rotated counterclockwise around the origin by 90^{\circ} to produce \triangle A^{\prime \prime} B^{\prime \prime} C^{\prime \prime}. Which of the following transformations will return \triangle A^{\prime \prime} B^{\prime \prime} C^{\prime \prime} to \triangle A B C ?

A. counterclockwise rotation around the origin by 90^{\circ}
B. clockwise rotation around the origin by 90^{\circ}
