Answer

Examples of erosional landforms are Chasms, Wave-Cut Platform, Sea Cliff, Sea Caves, Sea Arches, Stacks / Skarries / Chimney Rock, Blow Holes or Spouting Horns, etc.

Hook is an example of depositional landforms. Wave-cut platforms form when destructive waves hit against the cliff face, causing undercutting between the high and low water marks, mainly as a result of corrosion and hydraulic power, creating a wave-cut notch. This notch then enlarges into a cave.

The correct option is A.
