<u>Answer:</u>
<em>A. Mantle convection
</em>
<em></em>
<u>Explanation:</u>
Ridges are formed over the divergent plate boundaries, it can be pushed by the mantle plume volcanism originated by the core mantle boundary at the Asthenosphere region over the divergent plate boundary. Seafloor spreading is the one of the evidences of plate tectonics theory. Subduction of the plate is the result of ridge push and slab pull, oceanic plate is less dense so its under beneath the high denser continental plate.
The rigid motion concept can be used to define congruency. Congruency is a relation between shapes or figures. One shape is congruent to another if, and only if, you can turn the one shape into the other with a rigid motion
Hope this helps, have a good day ;)
