The correct answer is D. Benito Mussolini became prime minister of Italy in 1922, as the Italian king feared a civil war when fascists marched on Rome, so he named Mussolini prime minister.

Explanation:

The march on Rome was the paramilitary march led by the fascist followers of Mussolini towards the capital of Italy on October 28, 1922, with the primary aim of impressing the Liberal government then still in place and to put pressure on the political class.  

Although the march numbered less than 30,000 people, the king was more afraid of the civil war that the squadrists might provoke, while he did not see such a threat in fascism. On October 29, 1922, Mussolini was commissioned to assemble a cabinet, while about 25,000 Black Shirts marched toward Rome. Mussolini thus legally gained power, in accordance with the Italian constitution.
