How was Mussolini able to gain power in Italy?

Mussolini took advantage of Italy’s political instability and the government’s weakness after World War I. In 1922, his Fascist supporters threatened a march on Rome, and the king appointed Mussolini prime minister rather than risk a violent takeover. This makes B, “He led a coup to take over a weakened government,” the best choice, though his rise involved political pressure as well as force.
