The correct answer is:

**D. A trench results from subduction and forms on the ocean floor where the two plates meet.**

Trenches are typically formed at convergent plate boundaries, where one tectonic plate is being subducted beneath another. This creates deep valleys in the ocean floor known as oceanic trenches.
