Operation Olive
Operation Torch

A?

Yes, A.

The operation that led to the Allied forces breaking through the Gothic Line was Operation Olive. This operation was a coordinated offensive launched by the Allies, particularly the British Eighth Army, during World War II in the Italian Campaign.

To get this answer, you can start by understanding what the Gothic Line was. The Gothic Line was a German defensive line in Italy during World War II, stretching from the coast of the Adriatic Sea to the Apennine Mountains.

Next, you can eliminate the options that are not relevant to the Italian Campaign. Operation Torch was the Allied invasion of North Africa, which took place before the Italian Campaign. Operation Overlord was the codename for the Allied invasion of Normandy during the D-Day landings in France. Operation Barbarossa was the German invasion of the Soviet Union during World War II.

By process of elimination, the operation that led to the Allied forces breaking through the Gothic Line is Operation Olive.
