The Monument Honoring the Events That Occurred at the Battle

The monument honoring the events that occurred at the Battle of the Little Bighorn differs today from when it was erected in 1881 in that:

A) while it was initially named the Little Bighorn Battlefield National Monument, opposition groups were successful in changing the name to Custer Battlefield.
B) in 1881, it was thought that Indian warriors had slaughtered Custer and his army, and so it was that event that the monument depicted; today archaeology has shown that Custer and his men actually won the battle, and so the monument now depicts that event.
C) a new memorial now also honors the fallen Cheyenne, Lakota, and Arapaho warriors.
D) All of the answers are correct.
