  • A. Galápagos Spreading Center
    The Galápagos Spreading Center is a mid-ocean ridge segment in the eastern Pacific where tectonic plates diverge and new oceanic crust forms near the Galápagos Islands.
  • B. Gulf of Aden spreading center
    The Gulf of Aden spreading center is a tectonic plate boundary in the northwestern Indian Ocean where seafloor spreading occurs, linking the Red Sea rift to the Carlsberg Ridge and contributing to the opening of the Gulf of Aden.

  • D. Cocos–Nazca spreading center
    The Cocos–Nazca spreading center is a mid-ocean ridge in the eastern Pacific where tectonic divergence forms and separates the Cocos and Nazca plates.
  • E. Romanche Fracture Zone
    The Romanche Fracture Zone is a major transform fault and deep-sea fracture zone in the equatorial Atlantic Ocean that offsets the Mid-Atlantic Ridge and hosts one of the deepest points in the Atlantic basin.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
