TYPE EmpList
IS VARRAY(2) OF employees.employee_id%TYPE NOT NULL;
v_employees EmpList := EmpList();

SQL> VARIABLE x REFCURSOR
SQL> EXECUTE emp_data.get_emp(195,:x)
SQL> PRINT x
Which statement is true about the above scenario?
A. The package executes successfully and passes the required data to the host variable.
B. The package specification gives an error on compilation because cursor variable types cannot be defined in the specification.
C. The package specification gives an error on compilation because the cursor variable parameter was specified before you defined it.
D. The package executes successfully, but does not pass the required data to the host variable because the cursor is closed before the PRINT statement runs.
