Hello there! Assuming you meant possessive pronoun, and not passive pronoun, your answer would be B. Mine.
A passive pronoun isn't a thing, I was pretty sure on my own and confirmed it with a google search.
So, that being said, i believe you meant possessive pronoun. A possessive pronoun shows ownership.
Out of the options you provided, B would be the best answer, since mine shows that the option belongs to the speaker. You, They, and Me, are all used to address the reader, speaker or other characters. Regardless, none of these options would work because they don't show ownership, so yes, b is your correct answer.
Hope this helps, and have a great day!
