The accurate statement about ethnic groups in Southwest Asia is:
Arabs are the largest ethnic group in the region.
This is true as Arabs constitute a significant portion of the population across several countries in Southwest Asia. The other statements are not accurate for the reasons stated:
- "Arabs are the majority in every country." – This is false as there are countries where Arabs are not the majority.
- "Kurds make up the largest ethnic group on the Arabian Peninsula." – This is false; Arabs are the largest ethnic group on the Arabian Peninsula.
- "People in the same ethnic group follow the same religion." – This is not true as there are diverse religions within the same ethnic groups.
