D Correct answer
Explanation

The average human breathing rate is 12-16 breaths per minute at rest. Taking the higher end of normal range (about 16 breaths per minute), over 24 hours this equals 16 × 60 × 24 = 23,040 breaths, which closely matches option D (23,045). Breathing rate increases during activity and decreases during sleep.
