What is the capital of the United States?

The capital of the United States is Washington D.C. This city was specifically chosen as the capital and has served in this role since 1800, when the federal government moved there from Philadelphia. Washington D.C. is not only a political center but also houses important government institutions, including the White House, the Capitol, and the Supreme Court. The location was strategically selected to be distinct from the states to ensure a neutral ground for politics.

The other choices represent significant cities in the United States but do not serve as the capital. New York City, while historically important and once the capital in the late 18th century, lost that status when the capital was moved to Washington D.C. in 1800. Los Angeles is known for its entertainment industry and cultural impact, while Chicago is a major financial and cultural hub in the Midwest, but neither of these cities functions as the capital of the nation.
