Answer: (D)

Verified step by step guidance

1. Understand the concept of homeostasis: Homeostasis is the process by which the human body maintains a stable internal environment despite changes in external conditions.
2. Identify the key components of homeostasis: These include sensors (receptors), control centers (such as the brain), and effectors (muscles or glands) that work together to regulate the body's internal environment.
3. Recognize examples of homeostasis: Common examples include the regulation of body temperature, blood pH, and glucose levels, all of which are kept within a narrow range to ensure proper functioning.
4. Evaluate the options given in the problem: Consider how each option aligns with the definition and examples of homeostasis.
5. Select the option that best matches the definition of homeostasis: The correct choice is the one that describes maintaining a stable internal environment despite external changes.
