When nitrobezene is treated with `Br_2` in the presence of ` FeBr_2` the major product formed is m-bromonitro-benzene . Statements which are related to obtatining the m-isomer are :
A. The electron densitty on meta-carbon is more than that on ortho-and para -positons
B. The intemediate carbonium ion formed after intial attakc of ` Br^(o+)` at the meta-position is least destabnilise
C. Loss of aromaticity when ` Br^(o+)` attacks at the orth- and para -positions and not at meta-position.
D. Easier loss of ` H^(o+)` to regain aromaticity from the meta-position than fromm the ortho- and para-positions
