D Correct answer
Explanation

OUT parameters are specifically designed to pass values back from a procedure to the calling environment. IN parameters pass values into the procedure but cannot return values. VARCHAR2 and BOOLEAN are data types, not parameter modes. The OUT mode allows the procedure to send computed results back to the caller.
