Which of the following correctly orders these three events from earliest to latest: the formation of the Second Triumvirate; the assassination of Caesar; the Battle of Philippi?

Explanation

Caesar was assassinated in 44 BCE, the Second Triumvirate was formed in 43 BCE partly in response to that event, and the Battle of Philippi followed in 42 BCE, so the correct order is the assassination, then the triumvirate's formation, then Philippi. Placing the triumvirate or Philippi before the assassination misstates the sequence, since both were direct consequences of Caesar's death.
