All of them. Divergent (spreading ridges), convergent (subduction zones), and transform (strike-slip). An example of each include the following:
Divergent: Mid-Atlantic spreading ridge
Convergent: Cascade Arc
Transform: San Andreas Fault
along tectonic plate boundaries.
Volcanoes occur in the Earth's crust, specifically at tectonic plate boundaries where magma rises to the surface through cracks and weak points in the crust. This process can happen at divergent, convergent, and transform plate boundaries.
Plate tectonics.
Plate tectonics, the movement of the large pieces of the earth's crust, give rise to great stress along the boundaries of the plates. Wikipedia has a post on plate tectonics, and a link is provided.
Convergent plate boundaries.

plate tectonics
The outermost layer of the Earth is called the crust. The layer of the Earth where earthquakes occur is called the lithosphere, which includes the uppermost part of the mantle along with the crust. Earthquakes are commonly associated with tectonic plate boundaries where plates interact and generate seismic activity.
Plate Tectonics. The crust is in large, irregular plates shuffling around by new rock extruded from the upper Mantle in ocean plate boundaries, balanced by the loss of the fringes of the ocean-floor plates to subduction.
Tectonic plates are large sections of Earth's crust that are constantly moving. These plates float on the semi-fluid asthenosphere layer underneath, causing them to shift and interact with each other at plate boundaries, leading to geological phenomena like earthquakes and volcanic activity.
