confused about renosane stability

i thought C is the most stable because OH is an electron donator and prefers a + under it. 😕😕

what is the right answer? i'm trying to elminate some and so far i say it can't be B or D (F and O w/ + shoudln't look like that?). I'd guess E? The positive is furthest from the other stuff and the O has 2 sets of elecrons.

I could be totally wrong though, ochem is not my forte 😴

the answer is D. why is C wrong?

in the question they mention the octet rule so i assume that negative charge must be on the most electronegative atom and + charge must be on the less electronegative atom. is this correct?

there is pretty much teh same question in 163 of destroyer. The "extra" double bond makes it more resonance stabilized and therefore is a large part of the overall structure.

ohhh i skipped over this question because i thought i got it right.
