Correct answer: D — Both B and D are correct
C7 (vertebra prominens) has the most prominent spinous process of the cervical vertebrae — easily palpable at the base of the neck. It serves as a surface landmark for counting vertebral levels and identifying C7/T1. C7 also articulates with the first rib. Note: the vertebral artery typically enters the transverse foramen at C6 (not C7 — C7 transverse foramen is small or absent).
