B Correct answer
Explanation

Group functions like AVG and SUM can only be used on numeric columns that contain actual numeric data. They cannot be used on non-numeric data types (strings, dates, etc.) even if they appear numeric - the underlying data type matters. Additionally, these functions ignore NULL values in the numeric columns.
