Who cannot purchase firearms?

The correct answer is that individuals who are felons, drug users, mentally defective, illegal aliens, and persons under domestic restraining orders cannot legally purchase firearms. This is grounded in federal and state laws, which set restrictions on firearm ownership for individuals who fall into these categories due to concerns about public safety and risk of harm.

For instance, felons may pose a higher risk of committing violent crimes, while those categorized as mentally defective may not be capable of safely handling a firearm. Drug users are also restricted because their impaired judgment could lead to unsafe situations. Illegal aliens are prohibited from purchasing firearms as they do not have legal residency status, and those under domestic restraining orders are restricted to protect potential victims from further threats.

Other options, such as the blanket statement that all civilians cannot purchase firearms, is inaccurate, as many civilians can legally buy firearms if they meet specific criteria. The notion that only those with specific licenses can purchase firearms does not capture the complete legal framework surrounding gun ownership, as many can buy firearms without needing specialized licenses, provided they comply with necessary regulations. Finally, while there are age-related restrictions, saying anyone under 21 years old cannot purchase firearms is misleading, as laws vary significantly by state, with some permitting gun purchases
