The impact that Justinian I had on the Byzantine Empire, in an attempt to reunite the Roman Empire was that he rewrote the Roman legal code, which is the basis for civil law even today. Option B is correct.

Justinian I was the Eastern Roman emperor from 527 to 565. During his reign, Justinian sought to revive the empire's greatness and reconquer the lost western half of the historical Roman Empire. His rule constitutes a distinct epoch in the history of the Later Roman empire, and his reign is marked by the ambitious but only partly realized renovatio imperii, or "restoration of the Empire".
