    The correct answer is - theory of plate tectonics.

    Explanation:

    The theory of plate tectonics that outer shell OF of the earth is separated into several plates that spread over the mantle, the rocky inner layer. The plates are like a rigid and hard shell than to Earth's mantle.

    Sea-floor spreading is a divergent boundary that is causing 2 plates to move away from each other leads in spreading of the seafloor. It is because of convection currents moving plates.

    Thus, the correct answer is option D.

    Option A

    Continental Drift Theory

    This theory highlighted how big continents were broke down into smaller one It was discovered by Alfred Wegener in 1912.

    Some common evidences are movement of fossils remains

    for example -

    Fossil plant Glossolalia and reptile Lystrosaurus found today in South America, Africa, India, Antarctica, and Australia were part of Giant Gondwana Island which broke of from Pangaea about 200 million years ago. He also emphasizes that convection currents produced due to rising of hot rock over the mid-ocean ridges, and then sinks down as it cools and becomes denser. Due to this arrangement magnetism effect can be seen in earth crust
