Answer: (D)

Verified step by step guidance

1. Step 1: Begin by understanding the term 'body cavity.' A body cavity is a space within the body that houses and protects vital organs, such as the heart, lungs, and digestive organs.
2. Step 2: Review the options provided in the question. The term 'organ system' refers to a group of organs working together to perform specific functions, not a physical space. Therefore, it is not the correct answer.
3. Step 3: Consider the term 'membrane.' A membrane is a thin layer of tissue that covers or lines parts of the body, such as organs or cavities, but it is not a space itself. Thus, it is not the correct answer.
4. Step 4: Evaluate the term 'tissue.' Tissue refers to a group of cells that perform a specific function, such as muscle tissue or nervous tissue. It is not a space within the body, so it is not the correct answer.
5. Step 5: Conclude that the correct answer is 'body cavity,' as it specifically refers to a space within the body that contains and protects vital organs, such as the thoracic cavity, abdominal cavity, and pelvic cavity.
