Self-definition is basically defined as the process by which a person identifies himself and sees himself regardless of how others see this person and the standards that are set by others. It is a process that depends on self-reflection and introspection and it is guided in part by the standards and ideals that have been given by society as such. However, a person who undergoes the process of self-definition will try to define himself putting on the sides the expectations and view of the society he/she lives in. This is why the correct answer is D. Because in self-definition, what a person is doing is establishing who he/she is as an individual, their identity, taking into account the standards and ideals set by society, but not being framed rigidly by these standards.
