• A. Regulate and reabsorb carbonic acid to change and maintain pH
• B. Buffer acids through electrolyte changes
• C. Regenerate and reabsorb bicarbonate to maintain a stable pH
• D. Combine carbonic acid and bicarbonate to maintain a stable pH

Correct answer: C

Rationale: The correct answer is C. In renal failure, the kidneys lose the ability to regulate pH by controlling bicarbonate levels in the extracellular fluid (ECF). The kidneys can regenerate and reabsorb bicarbonate ions to maintain a stable pH. Choices A, B, and D are incorrect because the kidneys do not primarily regulate or reabsorb carbonic acid, buffer acids through electrolyte changes, or combine carbonic acid and bicarbonate to maintain pH. The key function of the kidneys in maintaining pH balance lies in the control of bicarbonate levels.
