Question

In which sentence is the predicate nominative correct? A. It is them. B. This is he. C. This is him. D. It is her.

Answer 1

The answer is B. This is he.

Think of how you might introduce a person (This is Brandon) and how Brandon would typically be replaced in a sentence. It sounds a bit off but it's the proper way to say it. 

Another hint is that This is him and It is her are both options and they can't both be right.
