Heat from deep in the Earth's interior is transferred to its crust by which of following ridges.

Mantle convection brings heat from deep in the mantle to the surface, where the heat released forms magmas that generate the oceanic crust. The midocean ridge axis is the site of active hydrothermal circulation and heat loss, forming black smoker chimneys and other vents.

Explanation:

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
