A point charge $q$ is placed at origin. Let $E _{A^{\prime}} E _{B}$ and $E _{C}$ be the electric fields at three points $A$ $(1,2,3), B(1,1,-1)$ and $C(2,2,2)$ respectively due to the charge $q$. Then, the relation between them is
1. $E _{A} \perp E _{B}$
2. $E _{A} \| E _{C}$
3. $\left| E _{B}\right|=4\left| E _{c}\right|$
4. $\left| E _{B}\right|=8\left| E _{c}\right|$
