The vertebral artery is formed by the fusion of the subclavian artery and the internal thoracic artery. It passes through the transverse foramina of the cervical vertebrae and enters the cranial cavity through the foramen magnum. The two vertebral arteries join to form the basilar artery at the level of the pons, which contributes to the blood supply of the brainstem and cerebellum. Therefore, choice D, the vertebral artery, contributes directly to the formation of the basilar artery.
