View the Exhibit and examine the description of EMPLOYEES and DEPARTMENTS tables.You want to display the EMPLOYEE_ID, LAST_NAME, and SALARY for the employees who get the maximum salary in their respective departments. The following SQL statement was written:WITH -SELECT employee_id, last_name, salaryFROM employees -WHERE (department_id, salary) = ANY (SELECT*FROM dept_max)dept_max as (SELECT d.department_id, max(salary)FROM departments d JOIN employees jON (d. department_id = j. department_id)GROUP BY d. department_id);Which statement is true regarding the execution and the output of this statement?

A. The statement would execute and give the desired results.
B. The statement would not execute because the = ANY comparison operator is used instead of=.
C. The statement would not execute because the main query block uses the query name before it is even created.
D. The statement would not execute because the comma is missing between the main query block and the query name.
