Answer:

Option (D)

Step-by-step explanation:

Two plates move towards one another in the case of a convergent plate boundary. Due to this, a subduction zone is created, where the heavier crust sinks below the lighter one. This zone of subduction is commonly identified by the presence of a narrow V-shaped depression known as deep-sea trench.

As the subducting denser plate reaches the layer of the asthenosphere, the rocks undergo partial melting, and the melt produced from it mixes with the magma. This magma eventually moves upwards to reach the surface in the over-riding plate giving rise to the formation of volcanoes.

The subduction zone and the oceanic trench are two of the common features present in the convergent plate boundary.

Thus, the correct answer is option (D).
