Powers of erosion:

-illustrates the power of wind, water, waves, and glaciers

I tried my best :D

I'm pretty sure Land-building is stronger than erosion. Land building refers to breaking up the land and using it for different purposes. And Land-building is stronger than erosion because when we build roads it increases erosion rates because it reduces the natural ground cover

a is the answer i believe.
