Origin of longissimus capitis?

Explanation:
Longissimus capitis starts from the transverse processes of the upper thoracic vertebrae and from the articular processes of the lower cervical vertebrae, then ascends to attach to the mastoid process of the temporal bone. This origin arrangement lets the muscle pull upward to extend and rotate the head. The other options don’t fit because they point to origins that belong to different muscles (spinous processes of the upper thoracic spine would be for other back muscles; the sacrum isn’t an origin for this muscle; and the occipital bone is where this muscle inserts, not where it originates).
