Answer:

The correct option is Trench

Explanation:

Trenches are formed by subduction. Trench are very deep, elongated cavities which border a continent or an island. Trenches are formed when one tectonic plate slides beneath another. When an ocean plate collides with another ocean plate then one plate will bend and slide under the other. This process is called subduction.
