In a graphical coordinate system for a window, the origin (0,0) is typically at the top left corner. The first value represents the x-coordinate (horizontal position) and increases to the right, while the second value represents the y-coordinate (vertical position) and increases downwards. Therefore, the lowest position on the left side would have an x-coordinate of 0 (far left) and the maximum y-coordinate value just before the height limit, which is 479 for a height of 480 pixels. This makes option C, (0, 479), the correct answer.
