Which statement about possessive pronouns is false? a: possessive pronouns may come before the nouns in sentences. b: possessive pronouns are spelled with apostrophes. c: possessive pronouns sometimes take the place of a noun. d: possessive pronouns act as adjectives when accompanied by a noun.

B
so like i don't exactly remember possessive pronouns, but from the name of them, it's like a pronouns taking possession of something. 
for possession a pronoun would be in the form of his,hers,or theirs. that object is (his/hers/theirs). so being used that way there is no apostrophe, the only way there would be one would be saying like they're, meaning they are, and that wouldn't be possessive. there's no way for any pronouns to have an 's and be possessive over an object.

Well, i'd need to see the poem that goes with this question
