E is definitely wrong, you can't group by salary alone. That would give you the average of the maximum salary for each unique salary value, which doesn't make much sense.

I think A and C are incorrect because they have some syntax errors. A is trying to use MAX() with AVG(), and C is trying to use SUM() with MAX().

The correct answers are B and D. B calculates the average of the maximum salaries for each department, and D calculates the sum of salaries for employees hired after January 1, 2019 for each department.

I'm not sure about option D. I think option B might also be correct because it groups by dept_id and salary.

I agree with Mirta. Option A and D seem to be the correct queries based on the description of the table.
