Chemical reactions and calculations

Which of the following reactions involve neither oxidation, non reduction ? 


Considering that oxidation involves increase in oxidation number while reduction involves decrease in oxidation number, in a redox reaction, we have: 

(a) Cr+6O42Cr2+6O72

(b) Cr2Cr+3Cl3

(c) Na0Na+

(d) 2S2+2O32S42.5O62

From above, we find that in reaction (a), neither the oxidation number of Cr increases nor decreases from +6.
