3. symmetrical petrous pyramids

A 1 and 2 only

B 1 and 3 only

D. 1, 2, and 3

Explanation:

Caldwell method explains that the radiographer must be able to see only petrous pyramids in lower third of the orbits, and also visualize similar distance from the lateral border of the skull to the lateral rim of the orbit bilaterally with symmetrical petrous pyramids when evaluating a PA axial projection of the skull with a 15-degree caudal angle.
