What is a wave-cut platform? a flat, bench-like surface a sand ridge a sandbar a ridge of sand projecting into a bay

Answer: ridge of sand projecting into a bay

Wave cut platform is a sloping rock ledge that originates from the shore side and extends to the bay. It's formation dependent upon the rock structure and it's type. The water in the bay causes abrasion of the rock. The solid massive rock such as granite is resistant to abrasion, and may prevent the formation of the platform. The wave-cut platform is formed by the abrasion of the weak and quickly eroding rocks, bearing constituents of sandy soil.

The answer is:

A ridge of sand projecting the bay.
