The accepted (and highly upvoted) answer to the question in the question What’s the rule for using “who” and “whom” correctly? states that the easiest way to find out whether to use who or whom is to try with he/him and see which fits.

But that doesn’t seem to fit very well in this case:

1. Who will it be?

2. Whom will it be?

If I replace with he/him there, it becomes:

3. Will it be he?

4. Will it be him?

– and I don’t know which of these is right, either. Is it really true that you can always associate who with he and whom with him? Or does that not always work? And which out of 3 and 4 is correct?
