Final Answer :
A
Explanation :
The standard deviation is a measure of the dispersion or spread of a set of data points. In Carmella's class, the scores are tightly clustered between 75 and 85, indicating a smaller spread and thus a lower standard deviation. In contrast, Conrad's class has scores ranging from 50 to 98, indicating a wider spread and thus a higher standard deviation.
