To find the answer to this question, we can start by understanding what utilitarianism is. Utilitarianism is an ethical theory that states the best action is the one that maximizes overall happiness or utility for the greatest number of people.

From the possible answer choices, we can eliminate option D as it states "None of the above." This leaves us with options A, B, and C.

Next, we need to determine which of these options accurately describes the principle promoted by utilitarianism. The principle of utilitarianism asserts that the best action is the one that brings about the greatest happiness for the greatest number of people.

Now, considering this information, we can determine that the rational, overriding principle promoted by utilitarianism is the greatest happiness principle. Therefore, the correct answer is B. greatest happiness principle.
