Durkheim claims that there are four kinds of suicide. These are egoistic, altruistic, anomic and fatalistic suicide. While the egoistic and the altruistic suicides are influenced by social integration levels, the anomic and the fatalistic suicides are influenced by moral regulation levels of the society. Very low levels of social integration are related to egoistic suicide. Egoistic suicide occurs when family, work and community ties weaken, people can not bound to social groups and find little social guidance about values, norms, traditions and goals. Because of the lack of social integration, they feel that they do not belong to the society. When bonds weaken due to loss of family, loss of friends, or a retirement, probability of egoistic suicide increases. Therefore, the correct option is B.
