B) Bromine is reduced and water is oxidized
C) Bromine is neither reduced nor oxidized
D) Bromine is both reduced and oxidised
Correct Answer: D
Solution :
[d] \[3\overset{0}{\mathop{B}}\,{{r}_{2}}+6C{{O}_{3}}^{2-}+3{{H}_{2}}O\to 5\overset{-1}{\mathop{B}}\,{{r}^{-}}+\overset{+5}{\mathop{B}}\,r{{O}^{-}}_{3}+6HC{{O}_{3.}}\]in this reaction bromine is oxidized as well as reduced.
