The process shown in this diagram is **subduction**, as it depicts the interaction between oceanic and continental plates where one plate is being forced below another.
Letter A in the diagram indicates a **convergent boundary** or **plate boundary contact**, where the ocean water meets land.
The oldest area in the diagram is **likely the lithosphere layer below land (C)**, as continental crust is generally older than oceanic crust. Inland areas tend to have older geological formations compared to the younger oceanic crust that gets continually formed at mid-ocean ridges.
