The ventral cavity, also known as the anterior cavity, encompasses the front of the body and contains several critical organs and systems. It includes the thoracic cavity, which houses the heart and lungs, and the abdominopelvic cavity, which contains digestive organs, reproductive organs, and the urinary bladder. Hence, identifying the ventral cavity as relating to the anterior surface of the torso accurately reflects its anatomical position and function within the human body.

The other choices do not comprehensively encompass the definition of the ventral cavity. The lower part of the body might suggest some abdominal or pelvic components but does not represent the broad scope of the ventral cavity. The back part and subdivisions refer more to the dorsal cavity, which includes the cranial and spinal cavities, while the cranial and spinal sections specifically describe the protective areas for the brain and spinal cord, respectively, aligning with the dorsal cavity rather than the ventral one.
