Verified step by step guidance

1. Step 1: Begin by understanding 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, thoracic cavity, abdominal cavity, and pelvic cavity.
2. Step 2: Review the contents of each body cavity. The cranial cavity contains the brain, the thoracic cavity houses the heart and lungs, the abdominal cavity contains organs such as the stomach, liver, and kidneys, and the pelvic cavity contains reproductive organs and parts of the digestive and urinary systems.
3. Step 3: Analyze the pairings provided in the question. Compare the listed cavity with its contents to determine if the pairing is anatomically correct.
4. Step 4: Eliminate incorrect pairings based on anatomical knowledge. For example, the thoracic cavity does not contain the kidneys, the abdominal cavity does not contain the lungs, and the pelvic cavity does not contain the heart.
5. Step 5: Confirm the correct pairing. The cranial cavity houses the brain, making 'Cranial cavity – brain' the correct answer.
