This is a good question.

One choice can be dismissed easily enough, which would that be, and why?

Actually, looking again, I do not know.

Certainly all of them can be true whether or not they need to be true is a different matter.

I am withdrawing my earlier assertion that one can be easily removed as the answer. I misread it.

Thinking about it now one at a time.

**I think all of them have to be true. **
