The ventral body cavity contains which major subdivisions?

Explanation:
The ventral (anterior) body cavity is divided into two main compartments: the thoracic cavity in the chest and the abdominopelvic cavity that extends from the diaphragm to the pelvis. This division, created by the diaphragm, is why the correct choice identifies the thoracic and abdominopelvic cavities as the major subdivisions. Within the thoracic cavity are smaller spaces like the pleural cavities (around the lungs) and the pericardial cavity (around the heart), but these are subdivisions inside the thoracic cavity, not the two broad divisions themselves. The dorsal body cavity, in contrast, contains the cranial and vertebral (spinal) cavities.
