The mean is the average of all the scores and is heavily affected by extreme scores, which in this case are the extremely low scores of the two students. The median isn't affected because it only takes the middle value, while the mode represents the most common score and isn't affected by two low scores. The standard deviation measures how much the scores vary from the mean, but it's not the most affected measure of central tendency in this case. Therefore, the best choice is A) mean.
