Answer:

The correct option is C: Posterior clinoid processes and dorsum sellae.

Explanation:

An Anteroposterior (AP) axial projection (Towne method) is a radiograph of the skull used to evaluate and demonstrate the presence or state of fractures.

Structures that can be seen are the entire occipital bone, the petrous part of the pyramids, and the foramen magnum. Through this last one, there can be seen the dorsum sellae and the posterior clinoid processes.
