Which movement demanded equal rights for African American people in USA ?

Correct option is B

The correct answer is (b) Civil Rights Movement.
The Civil Rights Movement was a mass protest movement against racial segregation and discrimination in the United States that came to national prominence during the mid-1950s. The movement's goals included desegregation of public schools, public accommodations, and employment, as well as voting rights for African Americans.
The Abolition Movement, which fought to end slavery in the United States, was active in the 18th and 19th centuries. The Labour Movement fought for the rights of workers, and the Women's Rights Movement fought for the rights of women.
Therefore, the Civil Rights Movement was the only one of these movements that specifically focused on the rights of African American people.
