316733 Iron is dropped in dil. \(\mathrm{HNO}_{3}\), it gives

1 ferric nitrate
2 ferric nitrate and \(\mathrm{NO}_{2}\)
3 ferrous nitrate and ammonium nitrate

316734 Statement A :
When a metal is treated with conc. \(\mathrm{HNO}_{3}\) it generally yields a nitrate, \(\mathrm{NO}_{2}\) and \(\mathrm{H}_{2} \mathrm{O}\).
Statement B :
Conc. \(\mathrm{HNO}_{3}\) reacts with metal and first produces a metal nitrate and nascent hydrogen. The nascent hydrogen then further reduces \(\mathrm{HNO}_{3}\) to \(\mathrm{NO}_{2}\).

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
