Correct answer: A
The mode of a data set is the value that occurs with the greatest frequency — the single most repeated observation among all the recorded values.
Count how many times each mark appears among the 16 recorded values:
0 appears 2 times
2 appears 2 times
3 appears 3 times
4 appears 1 time
5 appears 4 times
6 appears 2 times
7 appears 1 time
8 appears 1 time
As an independent check, these frequencies add up to 2 + 2 + 3 + 1 + 4 + 2 + 1 + 1 = 16, matching the total number of students, so no mark was missed or double-counted.
Since 5 occurs 4 times — more often than any other value in the list — the mode of this data set is 5.
