CorrectNot quiteAnswer D
Correct answer: D
Explanation
Count each size: 6 once, 7 three times, 8 four times, 9 once, 10 once.
Size 8 occurs most often, so the mode is 8.
Worth noting
4 is how many times size 8 was sold, not the size itself. 7.8 is the mean, which is not even a real shoe size here; the store stocks sizes, so the mode is the useful measure.
