Video Summary

The problem involves three boxes with incorrect labels each containing three balls. Mike must determine the contents correctly by drawing balls. Given that all labels are wrong, identifying the correct contents of one box will help conclude the configuration for all. By drawing two balls from the box labeled "two whites, one black," he can discern its true contents through a logical deduction process. Drawing either two whites or a black gives enough information to correctly label that box and the others, thanks to their mutual exclusivity. Thus, the smallest number of necessary draws is two, making option C the correct choice.
