Final answer:
During the Red Scare II, A. the movie industry was the first part of American society to be attacked.
Step-by-step explanation:
Red Scare II, also known as the Second Red Scare, occurred in the United States during the late 1940s and early 1950s. Fueled by anti-communist sentiments, it was marked by intense fear of communist infiltration and led to government investigations, blacklisting, and the McCarthy hearings targeting alleged subversives.
The first part of American society that was attacked because of the Red Scare II was the movie industry. During the Red Scare II, which took place in the 1950s, there was a widespread fear of communist influence and espionage. The House Un-American Activities Committee (HUAC) conducted investigations into alleged communist sympathizers in Hollywood, leading to the blacklisting of many actors, writers, directors, and other industry professionals.
