The correct answer is A) accusations of disloyalty, subversiveness, or treason without evidence.
The term "McCarthyism" means accusations of disloyalty, subversiveness, or treason without evidence.
During the 1950s, Wisconsin Senator Joseph McCarthy accused American officials and members of the US military of being Communists or having relationships with Communist. This started political persecution called the Red Scare. The problem was that the accusations lacked any support and McCartney hurt the reputation of many people.
