Why Would Promising Someone Money to Get Them to Give

Why would promising someone money to get them to give you a loan violate the categorical imperative, according to Kant?

A) Because the categorical imperative requires you to develop your talents and if you develop your talents enough, you will be able to convince someone to loan you money without lying.
B) Because the categorical imperative tells you how to achieve your goals, and assuming that your goal involves not breaking the law, the categorical imperative will not tell you to commit fraud.
C) Because you would be willing both that the person loans you money on the basis of your promise and that such promises would never work because no one would believe anyone's promises.
D) Because if you willed that everyone made false promises to secure loans, the financial system would collapse, causing even worse problems for you than you already had.
