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!
According to Coleridge's poem, the site is located in Xanadu, described as a savage place located where the Alph river ran through endless caverns featuring bright gardens and forests ancient as the hills with sunny spots of greenery, all holy and enchanted.
