Which cavity is commonly described as the lower portion of the abdominopelvic cavity?

Explanation:
Subdivision of the abdominopelvic cavity into upper and lower parts is what this question tests. The abdominal cavity forms the upper portion, holding most of the digestive organs, while the pelvic cavity is the lower portion, containing the reproductive organs, bladder, and rectum. The spinal cavity is a dorsal cavity that houses the spinal cord, separate from the abdominopelvic cavity, and the thoracic cavity lies above the diaphragm with organs like the heart and lungs. So the lower part of the abdominopelvic cavity is the pelvic cavity.
