B Correct answer
Explanation

Normal blood pH is tightly regulated between 7.35 and 7.45, which is slightly alkaline. This narrow range is critical for proper enzyme function and cellular processes. Option A (7.1-7.2) is too acidic and would indicate acidosis. Option D (7) is neutral pH, not physiological pH. Blood must maintain this specific alkaline range for survival.
