Which of the following years did Bart Connor NOT compete in the Olympics?

Bart Connor did not compete in the Olympics in 1980 due to the U.S. boycott of the Moscow Games. While he was a leading gymnast at that time, the political climate surrounding the Cold War led to the United States refusing to participate in the Olympic Games hosted by the Soviet Union. Connor went on to compete in the Olympics in 1984 in Los Angeles, where he won a gold medal, as well as in the 1988 Games in Seoul. He also participated in the 1992 Olympics in Barcelona. Thus, the year 1980 stands out as the only Olympics during which he was unable to compete due to the boycott.
