We Observe That There Is No Magnetic Force Exerted on a Moving

We observe that there is no magnetic force exerted on a moving charged particle.From this we can definitely conclude that

A) no magnetic field exists in that region of space.
B) the particle must be moving parallel to the $\vec { B }$ field vector.
C) the particle is moving at right angles to the $\vec { B }$ field vector.
D) either no magnetic field exists or the particle is moving parallel to the $\vec { B }$ field.
E) either no magnetic field exists or the particle is moving perpendicular to $\vec { B }$ the field.
