Who were the members of the Second Triumvirate?

The members of the Second Triumvirate were Marc Antony, Lepidus, and Octavian, which is why this choice is correct. The Second Triumvirate was formed in 43 BCE as a political alliance that aimed to consolidate power following the assassination of Julius Caesar in 44 BCE. This alliance was official and had legal standing, allowing these three leaders to divide the Roman territories among themselves and eliminate their enemies, particularly those loyal to the assassins of Caesar.

The significance of this triumvirate lies in its role in shaping the future of Rome, as it paved the way for the eventual rise of Octavian, who would become Augustus, the first emperor of Rome. Marc Antony is often remembered for his alliance with Cleopatra and his conflict with Octavian, while Lepidus served a more peripheral role in the power struggles that followed.

The other options listed represent different figures and alliances in Roman history that do not relate directly to the Second Triumvirate or its time period, highlighting the importance of understanding the specific context of Roman political structure during this era.
