Answer:
D) senators.
Explanation:
Although under his government the Republic experienced a brief period of great prosperity, some senators saw César as a tyrant who sought to restore the monarchy. In order to eliminate the threat posed by the dictator, a group of senators formed by some of his trusted men such as Brutus and Cassius and former lieutenants such as Trebonio and Tenth Brutus plotted a conspiracy in order to eliminate it. This plot culminated when, in the IDs of March, the conspirators murdered César in the Senate.
