Answer:

A. Mid Ocean Ridge.

Step-by-step explanation:

The correct answer is A.

A mid-ocean ridge is formed by plate tectonics and it is a type of a seafloor mountain system.

It occurs when tectonic plates separate at the ocean basin and magma flows out of the separation, forming a crust after cooling.

They usually have a depth of roughly 2500 meters and they rise about 2 km above the deepest part of an ocean basin.
