You can read in wikipedia that in planets with substantial atmposphere, the exosphere is the uppermost layer of the atmosphere where it merges with the interplanetary space (credit to wikipedia).
Then c. is the right option.
Slab pull does takes place at a convergent boundary and subduction zone. Slab pull therefore occurs because subducting slabs are cooler, and therefore more dense, than surrounding asthenosphere.
Subduction often takes place as a result of two plates colliding at a convergent boundary, and one plate is pushed beneath the other, back into the Earth's interior.
A oceanic plate hitting with a continental plate, will cause the denser oceanic plate to push or bent downward and slides under the edge of the continent.
Conclusively, the sinking of the tectonic plate makes the heat from beneath the Earth to melt.

Answer:
Deep underground, beneath an extinct volcano
Explanation:
Diorite results from the partial melting of a mafic rock above a subduction zone. It is found in volcanic arcs, and in cordilleran mountain building, such as in the Andes Mountains.
Diorite is formed <u><em>deep within the Earth's crust from cooling magma that never made it to the surface</em></u>. It usually occurs as quite small intrusions often associated with larger intrusions like granite. Slow cooling produces the large crystals.
Cold water upwellings help increase the number of organisms in an area by bringing more nutrients from the bottom. The correct option among all the options that are given in the question is the third option or the penultimate option or option "C". I hope that this is the answer that has come to your help.
