What is the capital of the United States?

The capital of the United States is Washington, D.C., which serves as the seat of the federal government and is home to key government institutions, including the White House, the Capitol Building, and the Supreme Court. This city was established as the nation's capital in 1790 and has significant historical and political importance.

The other choices represent major cities in the United States but are not the capital. New York City, while it is the largest city and a cultural and financial hub, was the first temporary capital of the United States before Washington, D.C. Los Angeles is known as a major center for entertainment and innovation, while Chicago is recognized for its rich history and economic contributions, but neither serves as the capital. Washington, D.C. was specifically chosen as a compromise location to represent its role as a neutral ground for the government, far from the influence of the existing states.
