Answer:

Option B, Divergent Boundary

Explanation:

The tectonic plates moving around form the divergent boundary and at this boundary magma from inside the earth rises to form new crust on the lithosphere beneath the water. Most of the divergent plate boundaries are present below the water where they form oceanic spreading ridges (submarine mountain ranges). The process of formation of oceanic spreading ridges is volcanic.

Hence, option B is correct
