Lots of batteries and a bulb

Identical batteries are connected in different arrangements to the same light bulb. Assume the batteries have negligible internal resistances. The positive terminal of each battery is marked with a plus. Rank these arrangements on the basis of bulb brightness from the highest to the lowest. Please explain your reasoning. (Most bulbs are brighter when there is more current through them. Assume that is the case for these bulbs.)
