The Posterior Surfaces of the Vertebral Bodies Are Demonstrated Without

The posterior surfaces of the vertebral bodies are demonstrated without superimposition on a left lateral lumbar vertebrae projection. The most magnified ribs are demonstrated posteriorly. How should the positioning setup be adjusted to obtain an optimal projection?

A) Rotate the side positioned farthest from the IR posteriorly until the midsagittal plane is perpendicular to the IR.
B) Rotate the right side anteriorly until the midcoronal plane is perpendicular to the IR.
C) Rotate the patient until the midsagittal plane is perpendicular to the IR.
D) Align the midsagittal plane parallel with the IR.
