To find the cumulative frequency for a score of 5, we need to add up all the frequencies for scores equal to or less than 5. In this case, we have 9 students with 5 or fewer absences, 7 students with 4 or fewer absences, 3 students with 3 or fewer absences, and 2 students with 2 or fewer absences. Adding these frequencies together, we get: 9 + 7 + 3 + 2 = 21. Therefore, the cumulative frequency for a score of 5 is 21. The best choice is B.
