d. shows that he was following the categorical imperative.

Explanation:

Kant advocated that people should do their duty from a sense of duty or what is morally correct. But sometimes it is difficult to judge what is morally correct. In case of uncertainty, we should be guided by the principle

of " categorical imperative". Its meaning basically is that, we should judge by thinking, what if everybody acts the way, I am thinking to do. If I think, taking bribe is right, what if everybody takes bribe. The outcome will be disastrous. So bribe taking can not be morally correct. This is how

" categorical imperative" works
