The correct answer is C) Italian.
Nicola Sacco and Bartolomeo Vanzetti were two Italian immigrants, workers, and anarchists in the US of the 1920s. They were accused of alleged theft and murder of two people in 1920 and executed by electrocution in 1927. Their case was very controversial worldwide, with many experts criticizing the judge Webster Thayer for being led by anti-immigrant, anti-Italian, and anti-anarchist feelings, spread by the fear of a possible Communist and/or Anarchist revolution.
