Final answer:
The Bourbon Triumvirate were influential post-Reconstruction politicians in Georgia and were prominent members of the Democratic Party, not the Whig, Populist, or any Roman-related political group.
Step-by-step explanation:
The Bourbon Triumvirate were three influential politicians from Georgia in the post-Reconstruction era, who spearheaded the Democratic Party's dominance in the state.
These men were not associated with any of the options provided such as the Whig Party, the populist leaders like Antony, Octavius, and Lepidus from Roman history, or the Populist Party. They were, in fact, members of the Democratic Party and represented the conservative interests of the planter elite and business class.
