Which describes how plague affected the byzantine empire?
a. it killed many residents.
b. it killed few residents.
c. it killed islamic invaders.
d. it killed emperor justinian i.

The correct answer for the question that is being presented above is this one: "D.It killed Emperor Justinian I." The plague affected the Byzantine Empire because it killed Emperor Justinian I. They caused widespread fear and disruption and began to change society. Medieval culture was beginning to break down, paving the way for the Renaissance and the modern world.

Again PinkFloyd's answer is incorrect. The outbreak of Bubonic plague in the Byzantine Empire was a horrific occurence as many thousands of people died (A - is the correct answer) but spared the lives of the court and the emperor. While Justinian was affected, he did survive the plague.
