The correct asnwer is B) Julius Caesar naming himself dictator and adopting his great nephew.  

In the year 45 BC, Julius Caesar named himself dictator, an exceptional political title of the Ancient Roman Republic that gave complete authority to a political figure during periods of conflict. Julius Caesar was extremely popular in Rome for all his military achievements and campaigns of conquest in Gaul. After that, he adopted his great-nephew Gaius Octavius as his heir.

This political movement marked the end of the Roman Republic and the beginning of the Roman Empire. After Julius Caesar was killed in a conspiracy, his great-nephew succeeded him as the first emperor: Augustus.
