According to NEC 430.24(A), the load of the highest-rated motor is calculated by adding the full-load current of each motor plus the greater of either the ampere rating from 430.22(E) or the largest continuous-duty motor full-load current multiplied by 1.25. Therefore, the correct answer is choice B - 1.25.
