Answer:
Option D, Between converging oceanic and continental plates
Step-by-step explanation:
Subduction zones/boundaries are formed in the regions in which one tectonic plate slips below the other tectonic plates. These tectonic plates could be a pair of oceanic/continental plates or one oceanic and one continental plate.
In a converging process, two tectonic plates move towards each other until they collide thereby causing slipping of one plate below the other. While in a diverging process, the two tectonic plates move away from each other and hence there is no chance of formation of subduction zone.
Thus, option D is correct.
