D. It is self-evident how we ought to behave in certain situations.
Explanation:
Sir William David Ross was a British philosopher known by numerous accomplishments, such as the <u>translations of Aristotle's work and the formulation of a new ethical theory</u>.
In this theory, Ross suggested that there are some critical rules or duties that should be followed, except if/when they conflict. These rules are also considered to be self-evident. He defined them as facie duties, which are: <em>fidelity, gratitude, reparation, justice, beneficence, non-maleficence </em>and<em> self-improvement</em>
