Hi there! The answer is C. barbarian raids.

Local farmers were unable to feed the Roman population during the fall of the Roman Empire because of barbarian raids. Between the 4th and 5th century, large groups of people entered the Roman Empire, which caused state failure inside the Empire. This period is called the Migration Period and preluded the Middle Ages.
