We only need to count the number of individuals who scored less than 3, i.e., the frequency of the scores 1 and 2. Adding the frequencies of these scores gives us 2 + 3 = 5, which means that 5 individuals failed the quiz. The best choice that represents this answer is option C, which gives the frequencies for scores 1, 2, and 3 (the passing score).
