A cubical region of side a has its centre at the origin. It encloses three fixed point charges, `-q` at `(0,-a//4,0)`, `+3q` at `(0, 0, 0)` and `-q` at `(0, +a//4, 0)`. Choose the correct options(s)

A

The net electric flux crossing the plane `x = + a/2` is equal to the net electric flux crossing the plane `x= - a/2`

B

The net electic flux crossing the plane ` y = + a/2` is more than the net electrc flux crossing the place ` y = - a/2`

C

The net elctric flux crossing the entre rggion is ` q/(varepsilon_0)`

D

The net electric flux crossing the plane ` z = + a/2` is equal to the net electric flux crossing the plane ` x = + a/2`
