Question

    Which theory about mantle dynamics was proposed by

    Arthur Holmes in the 1930s?  
    A Slab Pull Theory Correct Answer Incorrect Answer
    B Theory of Faunal Succession Correct Answer Incorrect Answer
    C Theory of Faulting Correct Answer Incorrect Answer
    D Convectional Current Theory Correct Answer Incorrect Answer
