While asking a previous question I was not sure whether to conclude by asking "A" or "B":

A. Which of the above definitions is the most accurate in describing ...

B. Which of the above definitions does it fit more accurately the meaning of "bombastic" in that interview.

In "B" case "does it fit" form (after "Which ...") caused me perplexity under a grammatical perspective.

Can anybody enlighten me on this problem?
