Step-by-step explanation:
The correct answer is A. necessary; comply.
In philosophy, the categorical imperative is a concept introduced by Immanuel Kant. It is a moral law that applies to all individuals and situations. Kant believed that actions should be done out of a sense of duty, and not based on personal desires or interests.
For example, if I have promised to meet a friend for lunch, the categorical imperative would require me to follow through with my promise, even if I don't feel like going. In this case, it is necessary for me to comply with the categorical imperative of keeping my promise.
