Correct option is C
In nitration of
benzoic acid, the
–COOH group is a meta-directing group due to its
electron-withdrawing nature.
When nitrated using
conc. HNO₃ and conc. H₂SO₄, the nitro group enters the
meta-position relative to the carboxylic acid group. Therefore, the major product is
m-nitro benzoic acid.
