Answer:
The answer is- nominative; subject
Step-by-step explanation:
A nominative case is a case of a noun or any other part of speech that acts as the subject of the given sentence.
Nominative pronouns are pronouns like I, you, he, she, it, they, and we. These pronouns are usually the subject of a sentence and perform the action in that sentence.
In the example above, He and I are nominative case pronouns and they are functioning as the subject in that sentence.
