The following is missing for the question to be complete:
A. Utilitarianism
B. Social responsibility
C. Consumerism
D. Preconventional morality
E. Distributive justice
Answer:    A. Utilitarianism
Explanation:  Utilitarianism is the doctrine according to which any procedure, rule, action, is good and useful if it suits the majority. According to this doctrine, the happiness and satisfaction of the majority should be the guide to which rules and norms should be harmonised. So, from the point of view of this doctrine, it is morally wrong to deprive most people of a popular student restaurant. It would be moral to meet the needs of the majority, to make the majority happy, and so the student restaurant would have usefulness, that is utility, hence the name of this doctrine. So the moral decision of what is good and what is wrong is made based on the outcome of the action or decision, and the outcome is good if it satisfies the majority.
