What cavity contains the spinal cord?

Explanation:
The spinal cord sits inside the vertebral cavity—the hollow canal formed by the vertebrae that runs within the spine. This vertebral (spinal) cavity is part of the dorsal body cavity, which also includes the cranial cavity that houses the brain. The other two cavities listed are in the ventral body cavity and contain different organs (the thoracic with heart and lungs, the abdominal with digestive organs) and do not enclose the spinal cord. So, the cavity that contains the spinal cord is the vertebral cavity.
