What is the capital of the United States?

Washington, D.C. is the capital of the United States because it serves as the seat of the federal government. Established by the Constitution and created specifically to be the nation’s capital, Washington, D.C. is where the three branches of government—the Executive, Legislative, and Judicial—are located. This city was chosen partly for its central location along the Potomac River, which facilitates access from various parts of the country. Over time, it has become a symbol of American democracy and governance, housing significant landmarks such as the White House, the United States Capitol, and the Supreme Court.

The other options, although significant cities in their own right, do not hold the same status in terms of governance or political importance as Washington, D.C. New York City, once the capital, is a major cultural and financial center, while Los Angeles is known for its entertainment industry, and Chicago is a key urban hub in the Midwest. None of these cities serve as the capital where the federal government operates.
