A
is oxidized and 
is reduced.
B
is oxidized and 
is reduced.
C
is both reduced and oxidised.
D
This is not a redox reaction.
Text Solution
Verified by ExpertsThe correct answer is:
A
Separating the oxidation and reduction reaction from the redox reaction:
assigning the oxidation number on central atom (N and Br) in each molecules by considering oxidation number of 
we get oxidation state as:
as the oxidation number of N changes from -2 to O as:
its a oxidation reaction where 
gets oxidized
Similarly, as the oxidation number of Br changes from +5 to -1 as:
its a reduction reaction where 
gets reduced
