Answer: (C)

Odontoid process

In human anatomy, the second cervical vertebra (C-2) of the spine is named the axis vertebrae. It forms the pivot upon which the first cervical vertebra (the atlas), which carries the head, rotates. The most distinctive characteristic of this bone is the strong odontoid process, known as the dens, which rises perpendicularly from the upper surface of the body.
