Couldn't this be a principle question?
I think what helped me see that D wasn't the correct answer is the fact that the answer makes a lot of assumptions, one being that more auditors is equivalent to increased likelihood of errors being detected. AND D doesn't even talk about an auditing procedure, it talks about the auditing departments of banks, essentially. The stimulus is about the likelihood of errors in banks' internal auditing procedures.
