Suicide occurs when people suffer a sudden dislocation of normative systems where their norms and values are no longer relevant, so that controls of society no longer restrain them from taking their lives.

The correct answer is anomic suicide. 

According to the sociologist, Emile Durkhiem, anomie refers to a phenomenon in which a person feels disconnected or separated from the norms, standards and ethics of the group or society they live in. An individual who experiences anomie, is likely to feel very isolated, distressed, disappointed and lacking in purpose. This in turn can lead to anomic suicide-  when people suffer a sudden dislocation of normative systems where their norms and values are no longer relevant, so that controls of society no longer restrain them from taking their lives.
