Final answer:
The Vandals traveled the greatest distance for their invasions, moving from present-day Poland through Europe and into North Africa, making them the group that covered the furthest during the period of their migrations. Therefore, the correct option is A.
Step-by-step explanation:
Among the groups mentioned, the Vandals traveled the greatest distance. Originating in present-day Poland, the Vandals crossed into Roman territory, pushed through Spain, and then conquered Roman North Africa. Their odyssey from Central Europe to the African coast was a journey of several thousand miles, spanning diverse geographic landscapes and challenges.
The Visigoths initially settled in southern Gaul and took control of much of Spain from the Vandals. In contrast, the Huns originated from the Eurasian Steppe and reached as far as Gaul under Attila’s rule, but their migratory path, while impressive, did not culminate in long-distance settlement like the Vandals'. Finally, the Ostrogoths, relative to the Vandals, did not cover as vast a distance. Consequently, the Vandals' long voyage marks them as the group that traveled the furthest distance during their invasions.
