What is the name of the national anthem?

The national anthem of the United States is called "The Star-Spangled Banner." This anthem was written by Francis Scott Key in 1814 and is based on his experience during the bombardment of Fort McHenry by British forces in the War of 1812. The song captures the resilience and bravery of the American spirit, particularly as it describes the sight of the American flag still flying after the battle.

"The Star-Spangled Banner" officially became the national anthem of the United States in 1931 through an act of Congress, symbolizing national pride and unity. The other choices listed, while patriotic songs, do not hold the official status of the national anthem. "America the Beautiful," "God Bless America," and "This Land is Your Land" are revered songs that evoke American themes and sentiments, but they serve different purposes and do not represent the nation in the same official capacity as "The Star-Spangled Banner."
