C Correct answer
Explanation

Niagara Falls erodes and moves backward due to water flowing over the escarpment, with rock wearing away over time. The falls have retreated approximately 11 kilometers since formation. The other landmarks (Burns Building, Fort Calgary, Nose Hill Park) do not have this characteristic backward movement.
