The correct answer is: "They are younger and form through the cooling of magma."
To arrive at this answer, we need to understand the formation of ocean rocks near mid-ocean ridges. Mid-ocean ridges are underwater mountain ranges where tectonic plates are pulling apart, allowing magma from the mantle to rise to the surface. As the magma cools and solidifies, it forms igneous rocks, which are rocks that are formed from the solidification of molten material.
Since mid-ocean ridges are active sites of volcanic activity, the rocks found near these ridges are relatively young because they have formed recently from the cooling of magma. This is in contrast to rocks found farther away from the ridges, which are generally older and have formed through different processes such as the cementation of sediments.
Therefore, the answer "They are younger and form through the cooling of magma" best describes the ocean rocks found near mid-ocean ridges.
