How was the protest at Wounded Knee similar to the protest at Alcatraz Island?

Both protests involved American Indians occupying a place to draw attention to their demands and grievances. Activists occupied Alcatraz Island from 1969 to 1971, and protesters occupied Wounded Knee in 1973. The protests did not both end peacefully, and Alcatraz was not the site of a former massacre, so A and C are incorrect.
