Solution

The statement that is FALSE is D. In line 5, the statement should not be corrected to front--. In a queue, data is removed from the front and added to the back. Therefore, when data is removed, the front should be incremented (front++), not decremented (front--). This is because the front of the queue moves forward, not backward, after a removal.
