It is b . Because three of them are less than 90.
When the material collides with the Earth's magnetic field and trapped radiation belts, it can dump particles into our upper atmosphere to cause the Aurora.
When this distorted magnetic field eventually snaps back, it accelerates electrified particles towards the Earth.
