Is it D?
Yes, the body primarily uses one negative feedback loop to maintain its temperature. Negative feedback loops work to oppose or reverse a change in the body's internal environment, bringing it back to a desired set-point. In this case, if the body temperature rises above the set-point, the negative feedback loop will activate mechanisms to lower the temperature (e.g., sweating, dilation of blood vessels). Similarly, if the body temperature drops below the set-point, the negative feedback loop will trigger mechanisms to raise the temperature (e.g., shivering, constriction of blood vessels).
