The maximum heart rate is calculated by removing the given age from 220. In this case, we are given 15 as the value for age. So, we have: 220 15 = 205.
To calculate the heart rate range, we have to calculate for three zones:
Zone 1= Maximum heart range * 0.6 = 205 * 0.6 = 123.
Zone 2 = Maximum heart range * 0.7 = 205 * 0.7 = 143.5.
Zone 3 = Maximum heart range * 0.8 = 205 * 0.8 = 164.
Therefore, the heart rate range = 123 - 164.
Thus, the correct option is B.
