The correct answer is B) Earth's magnetic field has reversed in the past.

Volcanic rock shows that some layers have magnetic fields that are aligned opposite to Earth's. This evidence BEST fits the hypothesis that the Earth's magnetic field has reversed in the past.

There is a field in science called Paleomagnetism that studies the rocks and the Earth's magnetic field. This serves geologists ti understand the magnetic changes in the Earth in the past. Volcanic and sedimentary rock sequences record geomagnetic reversals, that help scientists determine the Earth's condition thousands or millions of years ago.

A fear is being afraid of something, like climbing a mountain because you're afraid you might fall. But a phobia is an anxiety disorder and has to be diagnosed. Phobias don't pose a threat. Phobia would be a fear of the number 13 and getting anxiety when you see a 13 (it's a real phobia, too).
