The correct option is Convergent Boundaries.
Explanation
In Plate Tectonics, a Subduction Zone is a specific geological region where two lithospheric plates collide, and the denser plate sinks (subducts) beneath the less dense plate into the mantle. This process is integral to the recycling of the Earth's crust.
Option Analysis
- Divergent Boundaries is incorrect: Divergent Boundaries are locations where plates move apart from each other. This process leads to the upwelling of magma and the creation of new crust (constructive margins), such as in rift valleys or mid-ocean ridges, rather than subduction.
- Convergent Boundaries is correct: Convergent Boundaries involve the collision of tectonic plates. When an oceanic plate converges with a continental plate or another oceanic plate, the denser oceanic slab is forced downwards, creating a subduction zone. This is often marked by deep-ocean trenches and volcanic activity.
- Transform Boundaries is incorrect: Transform Boundaries occur where plates slide horizontally past one another. In these zones, crust is neither created nor destroyed (conservative margins), and vertical subduction does not occur.
- Mid-Oceanic Ridges is incorrect: Mid-Oceanic Ridges are characteristic features of divergent boundaries where sea-floor spreading occurs. They represent the generation of new crust, which is the opposite process of subduction.
Key Takeaway: Subduction zones are exclusively associated with convergent plate boundaries (destructive margins), where the destruction of the lithosphere takes place.
