PLS HURRY 25 points How do erosion and deposition work together to form sand dunes?

A: Waves cause erosion along coastlines and deposit sand away from the shore.
B: Erosion occurs as surface water carries sediment and the sediment is deposited near oceans and lakes.
C: Glaciers cause erosion through the movement of large chunks of ice, which are deposited and form depressions.
D: Erosion occurs through deflation, and sand that was picked up is deposited against an obstruction.
