    Option (4)

    Explanation:

    The mid-oceanic ridge refers to the middle portion of the sea and ocean. It is formed due to the divergent movement of two oceanic plates. Along this ridge, the magma erupts on the surface of the seafloor, thereby adding new materials to the crust. This is usually considered as the formation of a new ocean floor. These erupted rocks are mostly basaltic in nature. The rocks that are formed along this ridge are the youngest and the rocks that are formed away from this ridge are oldest.

    Thus, the new ocean floor is formed at the mid-oceanic ridge.

    Hence, the correct answer is option (4).
