Which sentence correctly uses a nominative case pronoun?

a. The referee at tonight's game will be I.

b. Eva and me are going in the same costumes.

c. Have you seen how well Ricky and her dance together?

d. The most dangerous animals are them.

The correct answer is D. Because it is the only correct sentence.

A isn't correct because it should be: The referee at tonight's game will be me.

B isn't correct because it should be: Eva and I ...

C isn't correct because it should be: Ricky and she ...

So the only answer left is D.

A.

Nominative pronouns are I, you, he, she, it, we, who, whoever, and they.
