Which additional figure joins Antony and Octavius to consolidate power?

• A. Marcus Agrippa
• B. Octavia
• C. Lepidus
• D. Portia

Answer: (C)

The main idea here is the formation of the Second Triumvirate, a formal alliance used to consolidate control after Caesar’s death. Lepidus joins Antony and Octavius to complete this power-sharing pact, giving them official authority to act together, to target their enemies, and to divide the spoils of Rome. Lepidus fits as the third member because he can be powerful enough to matter but not so dominant that he upsets the balance between Antony and Octavius; his inclusion helps present a united front and smooths the path to ruling. Marcus Agrippa becomes a key loyal ally later, but he isn’t part of the official Triumvirate at this stage. Octavia, while a political ally through marriage, does not co-rule. Portia has no role in this power consolidation. So Lepidus is the appropriate choice because he completes the Triumvirate that solidifies their joint grip on power.
