What is the reason for having 50 stars on the American flag?

The presence of 50 stars on the American flag is directly linked to the 50 states that make up the United States. Each star symbolizes one state, signifying the unity of the states within the nation. As new states were admitted to the Union, stars were added to the flag, which reflects the growth of the country over time. This design choice emphasizes the importance of each state as part of the collective identity of the United States.

Other options misinterpret the significance of the stars. They do not indicate major cities, represent presidents, nor relate to a specific number of years of independence, which reinforces the clarity and purpose behind the star representation corresponding to the states.
