Video Summary

The problem involves determining the initial combination of a bike lock based on the current displayed combination and knowing that each dial was turned the same amount. The current combination shown is 6-3-4-8. By analyzing different possible combinations and the consistent turning increments needed to reach each from 6-3-4-8, it is determined that options A, B, D, and E can all result from a uniform increment. However, option C does not follow the same pattern, as it requires inconsistent increments. Therefore, option C cannot be the original combination of the lock.
