Explanation:

Homeostasis in humans is not maintained by a single organ system. The endocrine system (hormonal regulation), nervous system (electrical - chemical signals), muscular system (e.g., shivering for temperature), and many other systems like the respiratory (gas exchange), circulatory (nutrient and waste transport), and excretory (waste removal) systems all work together. For example, to regulate body temperature, the nervous system detects changes, the endocrine system might release hormones, and the muscular system can generate heat. So multiple organ systems working together are responsible for maintaining homeostasis.

Answer:

C. Multiple organ systems working together
