An average heart rate is around 60-100 beats per minute, which means 3,600-6,000 beats per hour, and 86,400-144,000 beats per day. Multiplying the lower end of these ranges by 365 days in a year gives us approximately 31,536,000 beats per year. Multiplying this by 4 (as the answer choices suggest) gives us approximately 126,144,000 beats per year, which is closest to Choice C.
