Arrange the following concepts from most specific to most general: A) Ethnic identity, B) Race, C) Cultural heritage, D) Social categorization.

To arrange the concepts from most specific to most general, we start with ethnic identity, which refers to a person's sense of belonging to a particular ethnic group, often tied to shared culture, language, or traditions. Next, we move to cultural heritage, which encompasses the traditions, customs, and values passed down through generations within an ethnic group. Following that is race, a broader classification based on physical characteristics such as skin color and facial features, which can include multiple ethnic identities. Finally, social categorization is the most general concept, as it refers to the way society groups people into categories based on various traits, including race, ethnicity, and other characteristics. For example, a person might identify as having an ethnic identity of Irish, which is part of their cultural heritage, can be categorized racially as Caucasian, and ultimately be placed within the broader social categorization of individuals in society.
