Answer:
The correct answer is D. The Roman Republic didn't have a judicial branch.
Explanation:
After the fall of the monarchy the Republic was established in Rome, an aristocratic regime led by some forty gens; the patricians, the descendants of the oldest families in Rome held the power. The main institutions of the new regime were the Senate, the magistrates and the assembly.
The Senate was one of the pillars of the Republic, being the political organ that demanded responsibilities to the consuls. The auctoritas of the Senate gave validity to the agreements taken in the popular assemblies. The Senate also resolved cases of interregnum, a situation that occurred when one of the consuls died.
The Magistracy was an original charge of the Republic. The monarch was replaced by two collegiate and temporary magistrates called consuls who could be held responsible for their government duties. Each magistrate could veto the other, what was known as intercessio.
Also during the Republic popular assemblies, called Comitia Centuriata, were created. They were born due to military needs, in close connection with the expansion of the city and with the arrival in Rome of a new concept of military tactics. While in the monarchical era, the army was composed of members of the gens, in the Republic the army became a plutocratic system, dependent on the wealth of each subject. At first only the real estate wealth was estimated, but later the furniture was taken into account.
