A Uniform Electric Field $\overrightarrow { \mathbf { E } } _ { \mathrm { I } }$

A uniform electric field $\overrightarrow { \mathbf { E } } _ { \mathrm { I } }$ is present in the region between the infinite parallel planes of charge A and B,and a uniform electric field $\overrightarrow { \mathbf { E } } _ { \text {II} }$ is present in the region between the infinite parallel planes of charge B and C.When the planes are vertical and the fields are both non-zero,

A) $\overrightarrow { \mathbf { E } } _ { \mathrm { I } }$ and $\overrightarrow { \mathbf { E } } _ { \text {II } }$ are both directed to the right.
B) $\overrightarrow { \mathbf { E } } _ { \mathrm { I } }$ and $\overrightarrow { \mathbf { E } } _ { \text {II } }$ are both directed to the left.
C) $$\overrightarrow { \mathbf { E } } _ { \mathrm { I } }$$ points to the right and $$\overrightarrow { \mathbf { E } } _ { \text {II} }$$ to the left.
D) $\overrightarrow { \mathbf { E } } _ { \mathrm { I } }$ points to the left and $\overrightarrow { \mathbf { E } } _ { \text {II } }$ to the right.
E) Any one of the above is possible.
