C. only one absolute moral rule: the principle of utility.

Explanation:

In ethics, utilitarianism refers to a moral theory where the end result of attaining pleasure of happiness should be the single most important factor behind every action. First developed by philosopher Jeremy Bentham, he stated that the principle of utility should be the only absolute moral rule. this principle states that everything that increases happiness is good, and everything that produces the opposite of happiness is wrong. Utilitarians are thus concerned mostly with the end results, while the means are of a secondary nature and should only be judged by their capacity to increase happiness, not by whether they're good or bad.
