Correct option: A
(i) Br2/H2O  (ii)NaNO2/HCl−0∘  C  (iii) HBF4,Δ\left( {\text{i}} \right)\,B{r_2}/{H_2}O\,\,\left( {{\text{ii}}} \right)NaN{O_2}/HCl - {0^ \circ }\;C\,\,\left( {{\text{iii}}} \right)\,HB{F_4},\Delta
Option A (i) Br2/H2O  (ii)NaNO2/HCl−0∘  C  (iii) HBF4,Δ\left( {\text{i}} \right)\,B{r_2}/{H_2}O\,\,\left( {\text{{ii}}} \right)NaN{O_2}/HCl - {0^ \circ }\;C\,\,\left( {\text{{iii}}} \right)\,HB{F_4},\Delta is correct because it describes the correct sequence of reactions: bromination of aniline, diazotization, and then fluorination.
