Selected Answer: C
DISTINCTCOUNT as in Option A is definitively not calculating any averge but just how many different salaries there are in the table Similar, option B is calculation how many different salaries there are in the "Sales" Deptm Option D is calculating the total salary average in the company not just for the "Sales" department (and it could be affected by CONTEXT filters) In option C we are calculating the AVERAGE of the Salary, just for employees in SALES department and encapsulating calculation in CALCULATE to remove any report filter
