The question asks to write the chemical equation representing the cathode.
The electrolyte at the cathode is Na+, Cl-, O2 and H2O

What I would do is:
Na+ + Cl- + O2 + H2O --> NaClO2 + H2O
But that's obviously wrong. Please show me how to go about it.
Thanks!

it's relevant to standard denotations of the electrolytic cell, all of this should be explained very well in your text, so there's no point for any of us to reiterate everything to you here.
 
What process happens at the cathode - i.e. oxidation or reduction?
