As a result of Allied invasion of Italy in 1943, Mussolini was removed from power.

After the North African Campaign, the Allies decided that the next step should be the invasion of Italy, starting with Sicily. On July 10, 1943, led by Dwight Eisenhower, British and American troops landed on the south-east of the island and occupied it in little more than a month. The Allied invasion of Italian territory caused that, on July 24, the king of Italy Victor Emmanuel III ordered the arrest of Mussolini and named Marshal Pietro Badoglio as the new president of the country. The new Italian government immediately began talks for a peace agreement with the Allies that culminated on September 3 when the Armistice between Italy and the allied armed forces was signed.

The correct answer is option A.

The movement of Allied forces across the island of Sicily in the summer of 1943 resulted in the removal of Mussolini.

Explanation:

The Allied forces invaded the island of Sicily in Italy during Second World War on September 1943 after having successfully invaded North Africa. The invasion led to the ouster of the Italian dictator Benito Mussolini who led Italy against the Allied powers.  

Further Explanation:

Benito Mussolini was a fascist dictator of Italy who led Italy from 1925 to 1945. He was deposed of his powers and arrested when the Allied powers landed in Sicily and made attempts to invade Italy. Following this, Italy then signed an armistice with Allied powers and fought against the Axis for the remaining part of war.  The Axis were later defeated in the war with the defeat of Germany over Allied countries which involved U.S.A, U.S.S.R, England and France against the Axis power (Germany, Italy and Japan).
