Verified step by step guidance

Step 1: Understand the concept of body cavities. Body cavities are spaces within the body that house and protect internal organs. The major cavities include the cranial cavity, vertebral cavity, thoracic cavity, abdominal cavity, and pelvic cavity.

Step 2: Identify the location of the abdominal cavity. The abdominal cavity is located in the trunk of the body, below the thoracic cavity and above the pelvic cavity. It contains organs such as the stomach, liver, intestines, and kidneys.

Step 3: Determine the relative position of the thoracic cavity. The thoracic cavity is located directly superior (above) the abdominal cavity. It houses the lungs, heart, esophagus, and other structures within the rib cage.

Step 4: Compare the other options provided. The pelvic cavity is inferior (below) the abdominal cavity, the vertebral cavity runs along the spine, and the cranial cavity is located in the head, far superior to the abdominal cavity.

Step 5: Conclude that the thoracic cavity is the correct answer because it is directly superior to the abdominal cavity, based on anatomical positioning.
