Video Summary

The correct code for the lock, based on the given hints, is 042. The process involves deducing that digits 7, 3, 8 are unused, 6 is not in the correct place, and 0 is a correct digit but not in the middle. This leads to placing 0 at the start and ensuring 2 is in the third position. From hint two, the only possible correct digit for the middle is 4, as the other options (1 and 6) either contradict previous information or are eliminated. Thus, the lock code is 042, corresponding to answer choice D.
