Which of the following would most likely occur at a convergent boundary?

At a convergent boundary, two tectonic plates move towards each other, which can lead to significant geological activity. One of the primary outcomes of this interaction is the occurrence of earthquakes and volcanic activity. When an oceanic plate collides with a continental plate, the denser oceanic plate is usually subducted beneath the lighter continental plate. This subduction process generates intense pressure and friction, leading to the release of energy in the form of earthquakes.

Additionally, as the oceanic plate descends into the mantle, it melts and can lead to the formation of magma. This magma can rise to the surface, resulting in volcanic eruptions. Such geological processes are commonly observed along the Pacific Ring of Fire, a region with many convergent boundaries characterized by frequent earthquakes and active volcanoes. This makes it clear that convergent boundaries are primarily associated with seismic and volcanic activity, validating the selection of this answer. Other processes, like the formation of new crust or sedimentary rocks, occur at different types of boundaries and geological conditions.
