Answer:
The correct answer is B. The assassination of Dr. Martin Luther King Jr. largely contributed to the race riots of the 1960s.
Step-by-step explanation:
Until the 1960s, the race riots were mainly from whites. This changed with the African-American ghetto riots. In 1964 there were riots in Harlem, in 1965, in Watts. The next three years spared almost no big city in the United States. In the 1967 riots in Detroit, directed against white police violence, ended with 43 deaths. After the assassination of Martin Luther King on April 4, 1968, about 170 protests occurred in different cities, especially in Baltimore and Washington.
