Jun 16, 2016 at 5:16 comment added Martin - マーチン Resonance structures are not real, they are only a description. Therefore there cannot be a most stable resonance structure. The premise of the question is wrong, regardless of the error in the formulae. See also here.

Jun 19, 2015 at 17:09 comment added tkhanna42 Wow! I spent at least an hour on this question. I guess I should be more careful with my choice of text next time. @ron I can't believe I didn't see the mistake. Thanks.

Jun 19, 2015 at 16:47 comment added ron Possibly there's an error in the question. None of the 4 structures represent 1-methoxy-1,3-butadiene; all of the structures represent the dication of 1-methoxy-1,3-butadiene. I suspect someone accidentally put a (+) sign instead of a (-) sign in each structure. Had they been drawn correctly (with an equal number of positive and negative charges), then (c) would be the least stable since it has 4 separated charges, all of the others only have 2 (rules 1 and 2 in your list).
