Final Answer :
D
Explanation :
The mean is the best choice for examining average scores as it takes into account all values in the data set and is sensitive to changes in the values. The median and mode are not as useful for examining average scores as they only focus on one value in the data set and may not represent the overall trend. The standard deviation is a measure of variability, not central tendency.
