When convergent boundaries interact, the primary result is the formation of various geological features due to the collision and subduction of tectonic plates. The specific features that can occur include:

  1. Mountain Ranges: When two continental plates collide, they can create large mountain ranges (e.g., the Himalayas formed from the collision of the Indian and Eurasian plates).

  2. Trenches: When an oceanic plate converges with a continental plate, the denser oceanic plate often subducts beneath the continental plate, forming deep oceanic trenches (e.g., the Mariana Trench).

  3. Volcanic Arcs: The subduction of an oceanic plate under another plate can result in the formation of volcanic arcs (e.g., the Andes mountains).

  4. Earthquakes: The interaction at convergent boundaries can also lead to significant seismic activity, including powerful earthquakes.

From the options you provided, none of them specifically describe the primary features formed by convergent boundaries. However, the closest related phenomena might be:

  • Formation of island chains is often associated with volcanic activity at convergent boundaries (specifically between oceanic plates), resulting in volcanic island arcs (e.g., the Aleutian Islands).

Therefore, among the options, "formation of island chains" is the one that could relate to convergent boundaries, although this is more specific to oceanic-oceanic convergence rather than general convergent boundary interactions.
