The reaction proceeds as follows: 1. The anisole (methoxybenzene) undergoes nitration with \( \text{HNO}_3/\text{H}_2\text{SO}_4 \) to form the product (A), which is 4-nitroanisole. 2. Subsequently, bromination with \( \text{Br}_2 \) (in the presence of excess iron) results in the brominated product (B), 4-bromo-2-nitroanisole.
Thus, the major products are (A) and (B) as represented in option (2).

(A) N2(g) + O2(g) → 2NO(g) | (I) Decomposition |
(B) 2Pb (NO3)2(s) → 2PbO(s) + 4NO2(g) + O2(g) | (II) Displacement |
(C) 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g) | (III) Disproportionation |
