C

D
Thoracic cavity
Verified step by step guidance1
Step 1: Understand the major body cavities and what organs they typically contain. The main cavities include the cranial cavity (houses the brain), vertebral cavity (contains the spinal cord), thoracic cavity, and abdominopelvic cavity.
Step 2: Identify the organs mentioned in the problem: the heart, esophagus, and trachea. Consider where these organs are located anatomically within the body.
Step 3: Recall that the thoracic cavity is the part of the ventral body cavity located above the diaphragm and contains the lungs, heart, esophagus, and trachea.
Step 4: Compare the other options: the abdominopelvic cavity contains digestive organs and reproductive organs, the cranial cavity contains the brain, and the vertebral cavity contains the spinal cord, so these do not include all three organs mentioned.
Step 5: Conclude that the thoracic cavity is the correct body cavity that contains the heart, esophagus, and trachea based on anatomical location and organ contents.
