Final Answer :
C
Explanation :
The mean is the measure of central tendency used to calculate the average of a set of numbers, such as school grades. The mode represents the most frequently occurring grade, but may not accurately represent the average grade. The median is the middle value of a set of numbers, and may not accurately represent the average grade if there are extreme outliers. The standard deviation measures the amount of variation or spread within a set of numbers, but is not used to calculate the average grade.
