Good night to you too :) I hope you're doing well! :D
I'd go with B - Article. There are hundreds of good examples for the answer being B. For example, "a book" ('a' is an article - 'book' is a noun), "an apple" ('an' article - 'book' noun). Those are just the simple ones.
Your correct, It is B
Good Luck!
