Julius Caesar did many things that increased his popularity with poor and working-class Romans. For instance, he granted citizenship to people living in Rome's territories and he gave land to the poor. However, the most profound thing that he did was that he created new jobs, which meant new opportunities for the Romans. Hope this helped!
I believe the answer is: a republic as opposed to constitutional monarchy.
In constitutional monarchy, the country is still headed by the monarch as its central government, but the monarch must acted within the scope of the constitution.
The centrist argued that republic is a better form of government because it give the most power to the people that elected the government officials.
your answer would be A :)
