View the Exhibit and examine the data in the EMPLOYEES tables.Evaluate the following SQL statement:SELECT employee_id, department_idFROM employees -WHERE department_id= 50 ORDER BY department_idUNION -SELECT employee_id, department_idFROM employees -WHERE department_id= 90 -UNION -SELECT employee_id, department_idFROM employees -WHERE department_id= 10;What would be the outcome of the above SQL statement?
A. The statement would execute successfully and display all the rows in the ascending order of DEPARTMENT_ID.
B. The statement would execute successfully but it will ignore the ORDER BY clause and display the rows in random order.
C. The statement would not execute because the positional notation instead of the column name should be used with the ORDER BY clause.
D. The statement would not execute because the ORDER BY clause should appear only at the end of the SQL statement, that is, in the last SELECT statement.
