A drop in pH means the blood is becoming more acidic. The lower the number, the more acidic the pH. Acidity is a measure of H+ ions in the substance, so the blood becoming more acidic could be compensated by excreting more H+ and retaining more HCO3- (bicarbonate) ions. This would remove the excess H+ from the blood, which would cause the pH to rise, or become less acidic. Therefore, your answer is A.
