It is A...but coming from you it does not matter as the whole of your life is an illiterate post.
Sorry, you stupid fuck, but it's not. Nor is your constant use of "...." as punctuation anything remotely close to proper grammar. My, my, someone seems hell-bent on proving how ridiculously stupid they are. Did you make it out of elementary school? At this point, I seriously doubt you even have a GED.

Here's some help from Purdue University:
How do you know when to use the indefinite articles?"A" goes before all words that begin with consonants.
a cat
a dog
a purple onion
a buffalo
a big apple
With one exception: Use "an" before unsounded h.
an honorable peace
an honest error
"An" goes before all words that begin with vowels:
an apricot
an egg
an Indian
an orbit
an uprising
With two exceptions: When u makes the same sound as the y in you, or o makes the same sound as w in won, then a is used.
a union
a united front
a unicorn
a used napkin
a U.S. ship
a one-legged man
Note: The choice of article is actually based upon the phonetic (sound) quality of the first letter in a word, not on the orthographic (written) representation of the letter. If the first letter makes a vowel-type sound, you use "an"; if the first letter would make a consonant-type sound, you use "a." So, if you consider the rule from a phonetic perspective, there aren't any exceptions. Since the 'h' hasn't any phonetic representation, no audible sound, in the first exception, the sound that follows the article is a vowel; consequently, 'an' is used. In the second exception, the word-initial 'y' sound (unicorn) is actually a glide [j] phonetically, which has consonantal properties; consequently, it is treated as a consonant, requiring 'a'.
