A)Landward salt marsh migration increases
B)Nearshore sediment supply reduction
C)Offshore bar formations intensify
D)Coastal erosion from storm surge✓

Increased storm surge occurs because wave energy directly impacts the mainland, causing erosion; barrier islands dissipate wave energy via wave shoaling. Therefore less energy impacts the mainland, rather than energy absorbed further offshore.
