Somebody help me out

Answer:

$SecondOption$ - "Mid oceanic ridge"

Explanation:

<em> Mid-ocean ridges are formed by divergent plate boundaries in the ocean. This is where upwelling magma creates new seabed. A diverging plate boundary occurs when two plates move away from one other. Magma rises from deep beneath the Earth and erupts along these boundaries, forming new crust on the lithosphere. The majority of divergent plate borders are undersea, forming submerged mountain ranges known as oceanic spreading ridges. </em>

Hope this helps! :D
