Which One is The Right Article to Use For The Historic? Is it 'A Historic?' or 'An Historic?'

‘A’ and ‘An’ both are indefinite articles different forms of enunciation of words matter a lot such as when you mention a word that has “h” to start off with but is silent in enunciation you use ‘an’.

Example:

‘Hour,’ ‘Honor’ & ‘Honest’

When words that start off with consonant ‘H’ and also ‘H’ gets enunciated in pronunciation.

Example:

‘Hat,’ ‘Hotel,’ ‘Hard’

You should use “A” which means for the word historic it is better to use the article “A.”
