Ethnicity refers to a group defined by:

• A. Nationality, regional culture, ancestry
• B. Language alone
• C. Economic status
• D. Physical characteristics alone

Answer: (A)

Ethnicity is a group identity tied to shared culture, heritage, and social practices passed down through generations. The best option recognizes this by including nationality, regional culture, and ancestry, since it reflects legal or national background, the distinct customs of a geographic area, and family lineage that shape who people feel they belong to. Language can be part of ethnicity, but it isn’t the sole determinant, and economic status or physical traits do not define an ethnic group.
