Which of the following sites, one does not find in London?

Broadway

The correct answer is Option (4) → Broadway

Broadway is the one not typically considered a famous or iconic site in London in the same way as the others.

• White Hall (commonly spelled Whitehall) is a major street and government area in central London, home to key buildings like Downing Street and the Cenotaph.
• Hyde Park is one of London's largest and most famous Royal Parks, known for Speakers' Corner, the Serpentine, and events like Winter Wonderland.
• India House is the building housing the High Commission of India in London, located on Aldwych.

While there is a street called Broadway in Westminster (near St James's Park station, with notable buildings like 55 Broadway), and London's theatre district is the West End (often contrasted with New York's Broadway), "Broadway" as a renowned site or district is famously associated with New York City, not London.
