I have grammar test with the following question:
We are having an exam tomorrow. If we ______ to study, we would go out tonight. (A) Didn't have (B) Don't have (C) Hadn't (D) Hadn't have
That looks like a type II conditional sentence, but I can't extrapolate it's examples to this specific case.
Can you please point out the right choice here, and explain it? (I would like to hear the explanation for incorrect options as well.)
