Due to the earth's magnetic field, charged cosmic ray particles

Due to the earth’s magnetic field, charged cosmic ray particles :

a) Require greater kinetic energy to reach the equator than he poles
b) Require less kinetic energy to reach the equator than he poles
c) Can never reach the equator
d) Can never reach the poles

The answer to the question is : c) Can never reach the equator.

As the charged cosmic ray particles enter the magnetic field of the earth, they are deflected away from the equator.
