What term describes a group of people elected by citizens to choose a presidential candidate?

The term that accurately describes a group of people elected by citizens to choose a presidential candidate is the Electoral College. This institution plays a critical role in the United States presidential election process. When citizens vote in a presidential election, they are actually voting for a slate of electors pledged to a specific candidate. These electors then formally cast their votes for president and vice president in the Electoral College.

The significance of the Electoral College lies in its function as an intermediary that translates the popular vote into a definitive election outcome, reflecting the structured compromise inherent in the U.S. federal system of government. This process highlights the balance intended between populous and less populous states, as electors are apportioned based on a state's representation in Congress.

The other terms provided do not correctly represent this specific function within the election process.
