Final answer:
Orville Wright made the pioneering flight of 120 feet in 12 seconds on December 17, 1903. He and his brother Wilbur are credited with the first successful powered flight. Invention of the radio is attributed to Guglielmo Marconi, not related to the aviation achievement.
Step-by-step explanation:
On the morning of December 17, 1903, the correct answer for who flew 120 feet in 12 seconds is c) Orville Wright. Orville and his brother Wilbur were the pioneers behind the first controlled, powered, and sustained heavier-than-air human flight. Although Thomas Edison was a prolific inventor with contributions like the incandescent light bulb and the phonograph, and Alexander Graham Bell was famous for inventing the telephone, it was Orville Wright who achieved this aviation milestone. Inventing the radio is attributed to c) Guglielmo Marconi, not the individuals mentioned in the question relating to the flight. The skepticism around long-distance air travel was prevalent even among aviation pioneers like Orville Wright. However, Charles Lindbergh proved this skepticism wrong by flying solo across the Atlantic Ocean in 1927. Despite all this progress, the 1920s were just the beginning of what would become an extensive and transformative era of air travel.
