B is the best answer, contrary to popular belief. I've heard A spoken many times, and I've even found it listed as a variant in a dictionary (along with the main pronunciation shown in B), but most dictionaries don't say anything about a correct form of this word having the accent on the first syllable. C was my attempt to goof on people who might not know the word at all (and might think it's supposed to be a foreign word), and D was pretty much pulled out of my bum.
