A

Explanation:

When two plates collide, the denser one (usually the oceanic plate) gets subsided under the continental plate. There is very high friction between the two plates - because the plates a very rugged - consequently there is also high stress as the plates slip against one another. This causes the plates to bend at this subduction zone forming a trench.
