The joints between the vertebrae are secondary cartilaginous joints (symphyses) that are formed by the intervertebral discs between the vertebral bodies.
A symphysis is a type of joint that has a fibrocartilaginous disc between two bones that allows slight movement.
Choice A is incorrect because synarthrotic joints are immovable joints, such as the sutures of the skull.
Choice C is incorrect because sutures are fibrous joints that are found only in the skull.

Correct Answer is ["Mastoid process"]
Explanation
The mastoid process is a bony prominence located on the temporal bone of the skull, behind the ear.
It serves as an attachment site for several muscles, including the sternocleidomastoid and the splenius capitis.
The mastoid process also contains small air cells that are connected to the middle ear, which play a role in regulating the pressure within the ear.
In addition, the mastoid process is located in close proximity to several important structures, including the facial nerve, the internal jugular vein, and the sigmoid sinus.
Injuries to the mastoid process can occur as a result of trauma, infection, or tumors, and can cause pain, swelling, and other symptoms.
