Answer:
C). Seafloor spreading.
Explanation:
Paleomagnetism is characterized as the 'study of the account of direction and strength of magnetic fields of the Earth in sediments, rocks, etc.' The hypothesis that was authenticated by using this study would be 'seafloor spreading' by displaying that magnetic reversal as strips of rotating polarity in gradually disseminating seafloor. This description of magnetic stripping by employing paleo-magnetism made the scientists believe that alternate crusts are being frequently made under ocean/sea. Thus, <u>option C</u> is the correct answer.
