What is the capital of the United States?

The capital of the United States is Washington, D.C. This city was specifically selected as the nation's capital due to its strategic location along the Potomac River, providing a central point accessible from both the Northern and Southern states at the time of its establishment. Washington, D.C. officially became the capital in 1800 and has been the hub of the federal government ever since, housing significant government buildings such as the White House, the Capitol, and the Supreme Court. These facilities are essential for the functioning of the U.S. government and serve as symbols of American democracy.

The other choices represent significant cities in the United States but do not serve as the capital. New York, for instance, was the first capital following the ratification of the Constitution before the seat of government moved to Philadelphia and eventually to Washington, D.C. Los Angeles and Chicago are major urban centers known for their cultural contributions and economic power, but they do not hold the status of being the nation’s capital.
