Which best explains why earthquakes sometimes occur in the same locations as mid-ocean ridges and rift valleys?

A
Plates bump as they slip past each other at convergent boundaries.
B
Plates get stuck as they move past each other at convergent boundaries.
C
Crust gets cracked and forms faults as plates collide along divergent plate boundaries.
D
Faults form because crust gets cracked when plates move apart along divergent plate boundaries.

convergent boundary between two ocean plates
D
convergent boundary between two continental plates
