An AP axial sacral projection with poor positioning demonstrates that the symphysis pubis rotated toward the patient's right side. How was the positioning setup mispositioned for such a projection to be obtained?
A) The central ray was angled too cephalically.
B) The patient was in an RPO position.
C) The patient's legs were extended.
