Final answer:
The state quarter featuring only Wilbur Wright clearly visible is North Carolina's, reflecting its history as the site of the first successful powered flight.
Step-by-step explanation:
The state quarter that features one of the Wright brothers, with only Wilbur visible, represents North Carolina. The quarter design is based on the famous photograph of the first successful flight of a powered aircraft conducted by the Wright brothers on December 17, 1903, near Kitty Hawk, North Carolina. This monumental event marks North Carolina's significant contribution to aviation history, which is why the state is known as "First in Flight" and this slogan is featured on standard-issue North Carolina license plates.
