Option C, the Battle of Wounded Knee is the right answer.
The battle of Wounded Knee was last armed conflict that took place between the Native American and the army of the United States.
This battle burst out when the troops of the U.S blockaded and fired on a group of the native Americans near Wounded Knee Creek at South Dakota. Native Americans abandoned their weapons when asked by the U.S forces. But this fight only broke out when someone fired a bullet while the group was being unarmed. This battle soon turned into a massacre.
