What does each star on the U.S. flag represent?

Each star on the U.S. flag represents one state in the union. The current design of the flag includes 50 stars, corresponding to the 50 states that make up the United States. This symbolizes the unity of the states and their equal status within the country. The stars are arranged on a blue field known as the "Union," which signifies the federal aspect of the government and the collective identity of the individual states. This is an important aspect of the flag’s symbolism and reflects the history of the United States as it grew from the original 13 colonies into a federation of states. The other options do not accurately represent the symbolism of the stars, as the flag specifically highlights states rather than presidents, territories, or colonies.
