The correct answer option is Predicate Nominative.
<u>Explanation:</u>
We are given the following sentence:
'We get our paychecks on Friday and I always need mine'. Here in this case, the word 'mine' is acting as a predicate nominative.
A predicate nominative (which is also called a predicate noun) is a word or group of words which completes a linking verb and also renames the subject.
Here 'mine' is a pronoun which completes the linking verb 'need'.
