Martin Luther King Jr. advocated for nonviolent (peaceful) protests in order to gain civil rights for African-Americans. Malcolm X was similar in the sense that he wanted equal rights, however he was in favor of using violence in order to do this.
Another important Civil Rights leader was Rosa Parks. She refused to give up her seat to a white passenger in a "white only" section of a Montgomery Bus. This resulted in the Montgomery Bus Boycott, which helped end segregation on buses in Alabama.
John F. Kennedy was the man assassinated on November 1963. His assassin was Lee Harvey Oswald. Only one day after Kennedy was killed, Oswald was killed by a Dallas night club owner by the name of Jack Ruby. Even though Kennedy died, his legacy lived on when Lyndon B. Johnson was able to get the Civil Rights Act of 1964 passed. This was a document Kennedy worked on for a long time, unfortunately he was killed before it could pass in Congress.
The best answer would be B. :)
The Vicepresident of the U.S. is Constitutionally the "leader" of the U.S. Senate. In absence of the Vice President a President Pro Tempore is elected to replace him; custom makes that this Pro Tempore Presidency falls on the head of the most senior member of the party that holds a majority of seats.
