The correct option is A John Glenn
John Glenn was the first U.S. astronaut to orbit Earth, completing three orbits in 1962.
By orbiting the Earth, John Glenn showed that the United States could compete with the Soviet Union in the Cold War space race.
His mission of almost nine days on the space shuttle orbiter Discovery, launched Oct. 29, 1998, when he was 77, made him the oldest human to venture into space.
