Answer:
A. people wrongly accused others who, as a result, were convicted with little or no evidence of wrong doing
Step-by-step explanation:
Joseph McCarthy was a Senator representing Wisconsin who made accusations between 1950 to 1954 that some people within the government were supporters of Communism. This caused a scare as there was already distrust in the economy about communists and the Soviet Union. He even wrote to the President promoting this accusation.
This bears a great semblance to the Salem witch trials were a lot of people were accused of being witches and some even convicted, when in reality, the accusations were false.
