Answer:
An exclusion zone is established by a sanctioning body to prohibit specific activities in a specific geographic area for control of populations for safety, crowd control, or military purposes, for the last one, is established by a country to prevent the unauthorized entry of civilian personnel/equipment for their own safety or to protect natural assets already in place in the zone.
The correct option is option 2. The West Coast. Approximately 5,000 Japanese Americans relocated outside the exclusion zone before March 1942, while some 5,500 community leaders had been arrested immediately after the Pearl Harbor attack and thus were already in custody. The majority of nearly 130,000 Japanese Americans living in the U.S. mainland were forcibly relocated from their West Coast homes during the spring of 1942
