The correct answer is C.Balance in the body.

Homeostasis refers to the body's ability to maintain a stable internal environment despite changes in the external environment. This balance ensures that conditions such as temperature, pH, hydration, and the concentration of gases like oxygen and carbon dioxide, nutrients, and electrolytes remain within a narrow range that is optimal for cellular function and overall health.

Why the other options are incorrect:

A.How the body releases oxygen: This is a specific physiological process (e.g., oxygen is transported in the blood by hemoglobin), but it is not the definition of homeostasis. Homeostasis includes maintaining oxygen levels, not specifically releasing oxygen.

B.Passive transport: Pa...
