Question 3

DISTINCT option causes a group function to consider only the unique values of the argument expression.

Answer

True

Reason — The DISTINCT keyword, when used with group functions (such as COUNT, SUM, AVG), ensures that only unique values of the specified column or expression are considered in the calculation, thereby eliminating duplicates from the result set.
