Video Summary

The problem involves determining which numbers can be seen when a gray circle with two holes is placed over a clock face and rotated so the number 10 appears in one hole. Observing the pattern, when one hole shows a number, the other hole shows the number that is four hours ahead or behind. Therefore, if the number 10 is visible, the potential numbers for the other hole are 2 (four hours after) and 6 (four hours before). Thus, the possible numbers visible are 2 and 6, making option A the correct answer.
