In what year did Cicero serve as consul?

Cicero served as consul in 63 BC, which is well-documented in historical records. This year is significant in Cicero's life and Roman history because it was during his consulship that he famously uncovered and suppressed the conspiracy led by Catiline, which aimed to overthrow the Roman Republic. His actions during this period are seen as a pivotal moment in his political career, establishing him as a defender of the Republic and earning him widespread acclaim.

The other years listed do not correspond to Cicero's consulship. In 49 BC, he was not in office; instead, he was navigating the political turmoil surrounding Julius Caesar's rise. The years 76 BC and 70 BC were also prior to his consulship, with 70 BC marking a time when Cicero was emerging as a prominent orator and lawyer, but not yet holding the consulship. Thus, 63 BC stands out as the correct answer regarding his role as consul.
