High-energy solar particles are confined by Earth's magnetic field, creating what is known as the Van Allen belt. High-energy particles originate from the sun in the form of solar wind and from the universe in the form of cosmic rays. As these particles approach Earth, the magnetosphere acts as a net to keep them from reaching the surface. (option A). This is further explained below.
Generally, The Van Allen belt is created when high-energy particles from the sun are captured by the magnetic field of the earth, which creates the belt. High-energy particles may be traced back to the solar wind and cosmic rays as their origins. As these particles reach the globe, the magnetosphere of the earth captures and holds onto them.
In conclusion, Radiation bands up to 58,000 kilometers in diameter surround Earth and are collectively known as the Van Allen belts. Each of two zones of strong radiation partially encircling the globe at heights of several thousand kilometers, both of which are held in place by the earth's magnetic field and undergo periodic contraction and expansion when electrons are pushed between belts, into the atmosphere, or into space.
