Answer: (D)

Verified step by step guidance

1. Understand the role of carbon dioxide in the body: Carbon dioxide (CO2) is a waste product of cellular respiration, which needs to be eliminated from the body to maintain homeostasis.
2. Identify the primary organ systems involved in gas exchange: The respiratory system is responsible for the exchange of gases, including oxygen and carbon dioxide, between the blood and the external environment.
3. Examine the role of the circulatory system: The circulatory system transports carbon dioxide from the body's tissues to the lungs, where it can be expelled during exhalation.
4. Consider the function of the respiratory system: The respiratory system facilitates the removal of carbon dioxide from the blood by allowing it to be exhaled through the lungs.
5. Conclude the primary systems for CO2 elimination: The respiratory and circulatory systems work together to ensure carbon dioxide is efficiently removed from the body.
