Final answer:
Antagonistic negative feedback processes in homeostasis function to maintain stability by opposing deviations from a set point, hence restoring balance in the body's internal environment.
Step-by-step explanation:
The role of antagonistic negative feedback processes in the maintenance of homeostasis is crucial, as they serve to maintain stability and balance within the body's internal environment. The correct answer to the provided question is C) They oppose each other to maintain stability and balance. When a variable, such as blood glucose level or body temperature, deviates from its set point, negative feedback mechanisms act to counteract the change and bring the variable back within a normal range. If a level is too high, the body will act to bring it down, and if it is too low, the body will act to raise it. These mechanisms are the primary method by which the body regulates its internal conditions, keeping physiological variables within limits that are compatible with life.
