Consider two diffraction gratings with the same slit separation, the only difference being that one grating has 3 slits and the other 4 slits. If both gratings are illuminated with a beam of the same monochromatic light, both gratings produce the same separation between orders, but the orders are better defined with the 4- slit grating.
the grating with 4 slits produces the greater separation between orders.
both gratings produce the same separation between orders.
the grating with 3 slits produces the greater separation between orders.
