Answer:
A.
Step-by-step explanation:
At the time of their trial, Italian immigrants (and all immigrants entering the nation) faced an obscene amount of discrimination and abuse by American citizens, ranging from not being hired because of their ethnicity or because they were an immigrant, all the way to attacks and other scare tactics.
The Sacco & Vanzetti trial was a key example of this nativism. Nicola Sacco and Bartolomeo Vanzetti were Italian-born immigrants and anarchists who were arrested on charges of armed robbery and first-degree murder. There was very little strong evidence of their guilt, with the police not finding evidence of the money they stole, and other evidence being discredited. They were convicted and executed via electrocution.
In 1961, ballistic tests confirmed Sacco's gun was used to kill the guard during the robbery, but Vanzetti's guilt is still unsubstantiated.
