Answer:
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
