The mode is the number that appears most frequently in the data set. In this case, the number 4 appears three times, which is more than any other number. Therefore, the modal number of hours studied is 4. Option A (10) and B (25) both only appear twice, so they are not the mode. Option D (there is no mode) would only be correct if no number appeared more than once, but since 4 appears three times, there is a mode.
