I wrote out some listening scripts for Japanese junior high school teachers and used this phrase at the end to say it was the red one they would go with.
"The red one it is."

Then they came back with a couple questions:

What's the subject in this sentence?
I told them the subject is 'it'

Why do you bring 'the red one' to the front and what's the rule for invertion?
???

I told them we bring it to the front for emphasis, but as far as invertion, I'm lost because you can't say 'It is the red one.'

Anyone have any thoughts on this?
