Answer 2

Answer:

The answer is C.

Explanation:

The submentovertex or the full basal projection of the skull is used best to demonstrate the base of the skull or the base of cranium. In this method, the x-rays' direction is starting from under the chin and exiting at the vertex or the top of the skull.
