What does HUAC stand for?

The correct response is the House Un-American Activities Committee. This committee was established in 1938 and became particularly well-known during the early years of the Cold War. It was primarily focused on investigating alleged disloyalty and subversive activities among private citizens, public employees, and organizations suspected of having communist ties. The committee held numerous hearings that scrutinized various individuals in Hollywood, labor unions, and other sectors, often leading to accusations, blacklisting, and significant public controversy. The name accurately reflects its mission to investigate activities and affiliations deemed un-American, particularly during a time of heightened concern about communism in the United States. The other choices do not accurately represent the committee's established nomenclature or its historical function.
