Case-study approach stands on the opposite of comparative foreign policy approach. Whereas comparative foreign policy approach attempt to formulate a generalisable theory of foreign policy, case-study approach claims that each state has a unique foreign policy. The central belief in this approach is that any explanation of foreign policy behaviours through generalisations would cause the loss of unique factors that make up a foreign policy action and creating patterns, models and theories, and trying to fit the foreign policy behaviour of states into these, ignore the essence of foreign policy that is being explained (Tayfur, 1994, 126).

The correct answer is B.
