The correct answer is "D"
The theory of conflict is one of the great schools of modern sociological theory, it is considered as a development that occurred in reaction to the statics of structural functionalism. During the 1950s and 1960s the theory of conflict provided an alternative to structural functionalism, but it has recently been superseded by neo-Marxian theories. The theory of conflict is closely linked to the theory of games and studies and schools on negotiation.
Generally, different definitions of "social conflict" are offered, differences that draw our attention to complementary aspects of the concept: For example, Stephen Robbins's: "A process that starts when one party perceives that another has negatively affected it or that is about to negatively affect some of their interests "and that of Lewis A. Coser for whom social conflict is a struggle for values and for scarce status, power and resources, in the course of which the opponents want to neutralize, damage or eliminate their rivals. A conflict will be social when it transcends the individual and comes from the very structure of society.
