The answer is continental/ continental convergent.
Explanation:
Continental/ continental convergent are when two plates collide they a density lower than the mantle to prevent subduction and create mountains.
In these boundaries the earthquakes are deep and are powerful. The deepest earthquake occurs at plate collision.
The example for continental/ continental convergent is the famous Himalaya Mountain Range.
The oceanic crust converges in continental crust and denser plate is between the continental plates. This process is called subduction.
The continental/ continental convergent will not have any ocean trenches.
