Answer:
The blue shirt is mine.
Explanation:
Absolute possessive pronouns are pronouns that show possession of something or someone and that stand alone because they do not require an antecedent in order to be used, as most pronouns do, such as <em>my, your, their, his, her, </em>etc.
Furtheremore, the absolute possessive pronouns are 7: mine, yours, his, hers, its, ours, and theirs. So, <em>the blue shirt is </em><u><em>mine</em></u> is the one that has this type of pronoun because it has <em>mine</em> and it shows that "I" posses the blue shirt without even mentioning the antecedent.
The other sentence shows ownership as well, but "me" is not a possessive pronoun but an object pronoun that is the object of the preposition "to."
