Proponents of personalistic ethics argue that

A) the best way to achieve the greatest good is to closely follow a set of rules and principles.
B) the worth of a particular action is judged on the basis of the consequences it produces.
C) societies,organizations and cultures determine what is ethically appropriate and acceptable within that group.
D) everyone ought to decide for themselves what is right based on their conscience.
E) Rule utilitarians argue all of the above

Personalistic ethics emphasize the importance of individual conscience, and the idea that each person must decide for themselves what is right and wrong. This is consistent with choice D, which asserts that everyone ought to decide for themselves what is right based on their conscience. Choices A, B, and C all suggest that ethical judgments should be based on external standards or principles, whereas personalistic ethics emphasize the importance of an individual's own sense of right and wrong. Rule utilitarianism, which is not mentioned in the question, is a type of consequentialist ethics that emphasizes the importance of adhering to rules that tend to produce the greatest amount of good consequences overall.
