When nitrobenzene is treated with `Br_(2)` in presence of `FeBr_(3)`, the major product formed is `m-`bromo`-`nitrobenzene. Statement which is related to obtain the `m-`isomer is

A

The electron density on meta carbon is more than on ortho and para position

B

The intermediate cabonium ion formed after initial attack of `Br^(+)` attack the meta position is least destabilzed.

C

Loss of aromaticity when `Br^(+)` attacks at the ortho and para positions and not at meta position

D

Easler loss of `H^(+)` to regain aromaticity form the meta position than from ortho and para positon.
