Which best explains why barbarian groups were able to weaken the Byzantine Empire?

Of all the given explanations, the best explanation about the power of the barbarian groups over the Byzantine Empire is that the empire had a number of open areas that may be invaded by belligerent forces. Hence, Option D is correct.

Who are the barbarians?

The term "barbarians," which today is frequently used to describe uncivilised people or evil people and their evil activities, was first used in ancient Greece to describe individuals who were foreigners or who did not speak Greek.

The word's current meaning is very different from its Greek origins. In the New Testament of the Bible, St. Paul (from Tarsus; lived between A.D. 5 and A.D. 67) refers to non-Greeks as barbarians in the Hellenic sense of the word (Romans 1:14). He also uses it to describe someone who merely speak another language (1 Corinthians 14:11).

Therefore, Option D is correct.
