The first-person point of view is a literary device that allows readers to get to know that character's thoughts, feelings and motives. Because the narrator refers to himself with words like <em>I, me, my </em>and <em>mine</em>, the story is seen through his or her eyes. As a consequence, it is not impartial and it may suggest features which are unknown or unnoticeable to the narrator. For example, they might not realize they have a psychological condition.
I think the correct answer is C. The pronoun was used as the predicate nominative of the sentence. The predicate nominative is a pronoun or a noun which is next to a verb and it describes or renames the subject. It usually follows a linking verb or a verb phrase. For this case, it is followed by the verb phrase "was".
