Exam 1Z0-047 - What is the reason when you execute the statement it does not produce the desired output?

You want to display the EMPLOYEE_ID, FIRST_NAME, and DEPARTMENT_ID for all the employees who work in the same department and have the same manager as that of the employee having EMPLOYEE_ID 104. To accomplish the task, you execute the following SQL statement:

SELECT employee_id, first_name, department_id
FROM employees
WHERE (manager_id, department_id) =(SELECT department_id, manager_id FROM employees
WHERE employee_id = 104)
AND employee_id <> 104;

When you execute the statement it does not produce the desired output. What is the reason for this?

A.
The WHERE clause condition in the main query is using the = comparison operator, instead of EXISTS.

B.
The WHERE clause condition in the main query is using the = comparison operator, instead of the IN operator.

C.
The WHERE clause condition in the main query is using the = comparison operator, instead of the = ANY operator.
