Answer :
The Van Allen belts are created by the deflection of charged particles. Here's an explanation to help you understand:
1. The Van Allen belts are regions of high-energy charged particles held in place by Earth's magnetic field.
2. These belts are created when charged particles from the solar wind and cosmic rays are trapped by Earth's magnetic field.
3. As these charged particles enter the Earth's magnetic field, they are deflected towards the polar regions, where they spiral around the magnetic field lines, creating the Van Allen belts.
Therefore, the correct answer to the question is B. Deflection of charged particles.
