A Germanic tribes

A The Roman Empire in the East ended when they were attacked by Germanic tribes.

The correct answer is B) Byzantine.

To arrive at this answer, we need to have some knowledge of history. The Roman Empire, at its height, was divided into two parts: the Western Roman Empire, with its capital in Rome, and the Eastern Roman Empire, referred to as the Byzantine Empire, with its capital in Constantinople (now Istanbul).

The Western Roman Empire faced numerous challenges, including attacks from Germanic tribes, while the Eastern Roman Empire, or Byzantine Empire, enjoyed more stability for a longer period. However, the Byzantine Empire eventually faced a significant threat.

In the 15th century, the Byzantine Empire was attacked by the Ottoman Turks. The Ottoman Empire, led by Sultan Mehmed II, successfully conquered Constantinople in 1453. This event marked the end of the Byzantine Empire and its thousand-year-long existence as a political power.

So, to answer the question, the Roman Empire in the East ended when it was attacked by the Ottoman Turks, meaning the correct answer is B) Byzantine.
