The most dangerous and undetectable type of terrorism that involves domestic terrorists originating within the US but recruited from individuals outside is called:

• A. Right-wing terrorism
• B. Foreign-based terrorism
• C. Cyberterrorism
• D. Homegrown terrorism

Answer: (D)

Homegrown terrorism is when individuals who are living in the United States become radicalized and motivated to act, with recruitment or inspiration coming from outside groups or foreign sources. This combination—domestic origin with external recruitment—best fits the scenario described, because the threat originates within the country but is linked to actors or networks abroad. That connection can make such threats particularly dangerous and hard to detect, since the people involved may blend in with ordinary society while still being influenced by foreign groups. Other types described focus on different patterns: right-wing terrorism emphasizes domestic ideologies, foreign-based terrorism centers on actors based overseas, and cyberterrorism targets information systems rather than the recruitment path of individuals.
