The correct answer is (C) Stack. A stack is a vertical column of rock near the coast, formed by coastal erosion. It is typically created when a sea arch collapses. Tombolos, sand bars, and spits are all landforms created by the deposition of sand, gravel, or sediment along the coast.

Coastal landforms are shaped by either erosional or depositional processes of waves and currents. Stacks are features of coastal erosion.

Examples of coastal erosional features include cliffs, wave-cut platforms, sea caves, sea arches, and stacks. Examples of coastal depositional features include beaches, spits, bars, tombolos, and barrier islands.
