Answer: the correct answer is C.) major league baseball
Explanation: Jack Roosevelt Robinson was an American professional baseball player who became the first African American to play in Major League Baseball (MLB) in the modern era. Robinson cut the baseball color line when the Brooklyn Dodgers started him at first base on April 15, 1947. When the Dodgers signed Robinson, they heralded the end of racial segregation in professional baseball that had relegated black players to the Negro leagues since the 1880s. Robinson was inducted into the Baseball Hall of Fame in 1962.
