Unlike the First Triumvirate, the Second Triumvirate was
an informal alliance with no legal standing
formally established by law, granting its members official constitutional power✓Bonne réponse
a temporary military pact limited to a single campaign season
a religious college overseeing state sacrifices
Explication
A law passed in 43 BCE gave Caesar's adopted heir, Antony, and Lepidus formal authority as a three-man board to reconstitute the state, unlike the private First Triumvirate. The body was therefore neither an informal pact nor a religious college, and its fixed term extended beyond a single campaign season.
