Washington, D.C. serves as the capital city of the United States, established specifically to be the seat of the federal government. It was chosen as a compromise between northern and southern states when the capital was moved from Philadelphia. The city's designation as the capital allows it to host key government institutions such as the White House, the Capitol, and the Supreme Court. Additionally, Washington, D.C. is notable for its national monuments and memorials, reflecting the history and governance of the nation.

The other choices represent major cities in the U.S. but do not fulfill the role of the capital. New York City, while historically significant and once the capital, is primarily known as a cultural and financial hub. Los Angeles is recognized for its entertainment industry and is the second-most populous city in the country. Chicago, known for its architecture and cultural contributions, is not the capital but holds importance as a major U.S. city in the Midwest.
