Answer:
C. Black people in Montgomery succeeded in ending segregation on buses by working hard and not giving up on their protest.
Step-by-step explanation:
The bus boycott in Montgomery, Alabama took place between December 5, 1955 and Dec 20, 1956. It lasted for 381 days. It was the first large-scale demonstration in US against segregation of whites and blacks. During the protests, civil rights leaders like Rev. Martin Luther King, Jr became very prominent. The boycott was precipitated by Rosa Parks' refusal to stand for a white man in a bus. Rosa Parks is recognized for igniting the U.S. civil rights movement and she was recognized by the United States Congress as "the first lady of civil rights" and "the mother of the freedom movement".
The bus boycott with the ensuing protests triggered the U.S. Supreme Court to declare in 1956 that Montgomery’s segregation laws on buses were unconstitutional and therefore null and void.
