What is the correct description of the magnitude and direction of the net force acting on a high-speed electron in space far from all material objects and free of electric and magnetic fields?

Options

1. AZero force, since there are no material objects, electric fields, or magnetic fields in space.
2. BA force in the direction of the electron's velocity, since it has kinetic energy.
3. CA force in the opposite direction of the electron's velocity, slowing it down.
4. DA force perpendicular to the electron's velocity, causing it to change direction.
