PLS HELP

How do magnetic patterns in the rocks along the mid-oceanic ridges explain seafloor spreading?


AAs oceanic crust sank beneath continental crust, the cooling rocks aligned with the earth's magnetic field, which periodically reversed. This periodic pattern was seen on one side of a mid-oceanic ridge.  

BAs new crust was added to the seafloor, the cooling rocks aligned with the earth's magnetic field, which periodically reversed. This periodic pattern was seen on one side of a mid-oceanic ridge.  

CAs new crust was added to the seafloor, the cooling rocks aligned with the earth's magnetic field, which periodically reversed. This periodic pattern was symmetrical on both sides of a mid-oceanic ridge.  

DAs oceanic crust sank beneath other oceanic crust, the cooling rocks aligned with the earth's magnetic field, which periodically reversed. This periodic pattern was seen on one side of a mid-oceanic ridge

The answer is C I just did the test and this was the correct answe hope this helped
