The correct answer is B. Cincinnatus accepted the role of dictator in a crisis and then gave up his power; Caesar used a crisis to gain power and then made himself dictator for life.
Explanation:
Cincinnatus was a Roman dictator and military leader that lived from 519 to 430 BC during his life Cincinnatus mainly work in his farm, but after an invasion that led to the crisis of the Republic and the people request of having Cincinnatus as a leader he was in charge of all the state and became the dictator for some years, however, one the crisis was over Cincinnatus decided to go back to the farm. On the other hand, Caesar, who was also a dictator and politician of the Roman Empire and lived from 100 TO 44 BC became the leader of the state due to his accomplishments during the crisis of the Republic including the Gallic Wars he used to become the first general fo the Republic and later the leader of the state, role that he kept until his death.
This implies both Cincinnatus and Caesar were dictators during the Roman Republic, but the way they get to the power was different, while Cinncinnatus was asked to be a dictator due to a crisis, Caesar used the crisis (war) to gain the power. Thus, the statement that describes the difference between Cincinnatus and Julius Caesar is "Cincinnatus accepted the role of dictator in a crisis and then gave up his power; Caesar used a crisis to gain power and then made himself dictator for life".
