When a charged particle moving with velocity $\vec{v}$ is subjected to a magnetic field of induction $\vec{B}$, the force on it is non-zero. This implies that:

1. A
   angle between $\vec{v}$ and $\vec{B}$ is necessarily $90^{\circ }$.
2. B
   angle between $\vec{v}$ and $\vec{B}$ can have any value other than $90^{\circ }$.
3. C
   angle between $\vec{v}$ and $\vec{B}$ can have any value other than zero and $180^{\circ }$.
4. D
   angle between $\vec{v}$ and $\vec{B}$ is either zero or $180^{\circ }$.
