When was the Empire State Building completed?

The Empire State Building was completed in 1931, marking a significant achievement in architecture and engineering at the time. It was officially opened on May 1, 1931, after construction began in 1930. Known for its Art Deco design, the building quickly became an iconic symbol of New York City and was the tallest building in the world until the completion of the World Trade Center in 1975. Its completion during the Great Depression also represented a bold statement of hope and perseverance. The other dates mentioned do not align with the building's construction timeline, making 1931 the only correct choice.
