What body cavity contains the brain and spinal cord?

Explanation:
The central nervous system is protected within the dorsal body cavity. This cavity includes two subdivisions: the cranial cavity, which houses the brain, and the spinal cavity, which houses the spinal cord. Together, they form the dorsal body cavity that contains both brain and spinal cord. The ventral body cavity holds the body's organs (thoracic and abdominopelvic regions) and does not enclose the brain or spinal cord. The cranial cavity alone contains only the brain, and the spinal cavity alone contains only the spinal cord. Therefore, the dorsal body cavity is the correct choice.
