The correct answer is D.
 An<em> ethical dilemma</em> (paradox)  is a decision making problem where the decision is based on moral values or beliefs of the people involved in making this decision. Examples of ethical dilemma are : abortion, putting the elderly in nursing homes, obligatory military service or stealing money to feed a hungry child. Such dilemmas do not have a simple, one way solution because there are always pro and contra arguments for each outcome.
The first step in solving ethical dilemma is to <em>identify the problems</em> and to make sure they are genuine and based on real facts. All given information must be verified and not based on rumors and gossip. It is important to establish if there is a real conflict of values/issues that is to be discussed.
