A) can never be justified by Act Utilitarianism.
B) can never be justified by Rule Utilitarianism

D) cannot be evaluated by that theory

Utilitarian theory assesses the morality of an action based on its ability to bring about maximum happiness or pleasure for the greatest number of people. In some circumstances, euthanasia of a terminally ill, suffering person who asks to be killed can be justified by utilitarian theory if it results in the greatest overall happiness or pleasure. This does not mean that euthanasia is always morally permissible, but rather that it depends on the particular circumstances and the potential consequences of the action. Thus, option C is the best choice.
