What did you discover about the polarity of rocks on the ocean floor near the Mid Atlantic Ridge? pls help its for an essay due soon

Explanation:

When lava gets erupted at the mid-ocean ridge axis it cools and turns into hard rock. As it cools it becomes permanently magnetized in the direction of the Earth’s magnetic field.Less than 60 years ago, scientists discovered that the Earth’s magnetic field has reversed its polarity (direction) hundreds of times during the past several hundred million years. A polarity reversal means that the magnetic North flips to where we know the South Pole is. At the mid-ocean ridge spreading axis, these flips in the direction of the Earth’s magnetic field are recorded in the magnetization of the lava. This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges.

These patterns of stripes provide the history of seafloor spreading. Geophysicists can read these patterns from the magnetic anomalies they measure with a magnetometer. Where the magnetic wiggles, or anomalies, are broader, the spreading rate has been faster. At slow spreading ridges, the anomalies are squeezed tighter together, but the basic patterns are quite similar so scientists can correlate or relate the magnetic wiggles to different parts of the global mid-ocean ridge.

i believe it is a.) released into

i wish i could but this one is weird give me abc and i can solve it.
