  1. Average oxidation number of $S$ atom is $+2$
  2. Oxidation number of two $S$ atoms is zero each and that of other two is $+5$ each
  3. Oxidation number of two $\mathrm{S}$ atoms is $+1$ each and that of other two is $+4$ each
  4. None of these

Solution

$\mathrm{Na}_{2} \mathrm{~S}_{4} \mathrm{O}_{6}$ has the structure :


O.N. of two $S^{*}$ atoms are $+5$ each and that of other two S atoms is zero each. *
