The middle one is the only correct one for how it is pronounced. The accent gives it the 'ay' sound. We don't say 'Rayzooay' in English. They do in French, though, which is why both e's are accented in French.

For the same reason, dropping the accents makes the e silent, and it becomes the word 'resume', as in to continue or restart something. That's a completely different word with a different meaning.

Resumé is the only way to spell it that makes it correct to the way it is pronounced in English - any other way is wrong in English (though accenting both e's is correct in French, as they pronounce the word differently.)
