Which of the following is not considered to be an ethnic group? a. African-American c. Jewish b. German d. Mongoloic Please select the best answer from the choices provided A B C D

The correct answer is D. Mongoloic.<br /><br />Explanation: Ethnic groups are typically defined as groups of people who share a common and distinctive culture, religion, language, or other characteristics. African-American, Jewish, and German are all recognized ethnic groups based on their shared cultural, historical, and social characteristics. However, "Mongoloic" is not a recognized ethnic group. It appears to be a misspelling or a fictional term, and it does not correspond to any known ethnic group in the real world.
