C Correct answer
Explanation

Grouping (aggregate) functions operate on sets of values and return a single result. AVG, COUNT, and MIN are all standard SQL aggregate functions used with GROUP BY. ABS is a single-row numeric function that returns the absolute value of one number - it does NOT group or aggregate data, making it the correct answer.
