The correct answer is B.

The Ghost Dance was a religious movement that started in 1889 and swept across Native American populations in the West.

It was a mystical ritual first but it became a political movement and a symbol of American Indian resistance to a way of life imposed by the U.S government. The dance was believed to reunite the living with the spirits of the dead, bringing the spirits to fight on their behalf.
