Which of the following would disqualify a third party from participating in sending a message via an amateur station?

Third-party rules generally allow unlicensed individuals to participate in amateur radio communications, provided a licensed control operator is present at the control point and strictly supervising the contact. However, FCC rules explicitly prohibit anyone whose amateur license has been suspended or revoked from participating as a third party. This regulation is designed to prevent individuals who have legally lost their operating privileges due to violations from bypassing the system by simply using someone else's station. Citizenship and spoken language do not restrict a person from being a third party, as amateur radio is international and open to people of all backgrounds.
