B Correct answer
Explanation

The average human blinks approximately 15,000 to 20,000 times per day, which translates to about 15-20 blinks per minute. Blinking is essential for eye health as it spreads tears, removes debris, and prevents dryness. The rate can vary based on activities (reading reduces blinking, screen time may affect it), but 20,000 falls within the scientifically accepted normal range.
