Answer:
Option B, majority rule, is the right answer.
Step-by-step explanation:
The Fifteenth Amendment to the Constitution of the United States is very significant in the history of the United States. It was the amendment that prohibited all the governing bodies at the federal and the state level from denying the right to vote to a citizen on the basis of their "color, race or their previous condition of servitude".
The Fifteenth Amendment was an amendment that granted the right to vote to the African-American men. However, unfair practices were employed to prevent blacks from practicing their right to vote, in the later phase of the 1870's. Moreover, the African-Americans could only exercise their right to vote after the Voting Rights Act of 1965. Therefore, it may be said that this amendment influenced the majority rule democratic principle.
