The correct match is A-(iii), B-(i), C-(ii), D-(iv).
. In the reaction of sodium peroxide with sulphuric acid, the oxidation numbers of all the species remains same. Hence, it is non-redox reaction.
In the reaction of hydrogen with chlorine to form hydrogen chloride, hydrogen is oxidised and chlorine is reduced. Thus, it is a redox reaction.
During conversion of chromium trihydroxide to chromate ion, the oxidation number of chromium changes from +3 to +6 . Hence, chromium is oxidised.
During conversion of 
to 
, the oxidation number of iodine changes from +5 to -1 . Thus, iodine is reduced in this reaction.
