Answer:
D. Had political rulers called consuls.
Explanation:
After the Romans eliminated the Consul position when they became an empire in 27 BC, there wasn't really a such thing as a consul until 1722, when Great Britain appointed them to the Republic of Genoa. That was a full 269 years after the Byzantine Empire ended. The equivalence of a consul (which was the highest rank of power during the Roman Republic era) in the Byzantine Empire was a Eunuch (pronounced YOO-nuhk).
