Calculate the correct increasing order of average oxidation number of sulphur in

$S_8,\,S_2O_3^{2-},\, S_2O_7^{-2},\, S_4O_6^{-2},\, SO_3^{-2}$

  • ${S_8} < {S_2}O_3^{ - 2} < {S_4}O_6^{ - 2} < SO_3^{-2} < {S_2}O_7^{ - 2}$
  • B
    ${S_2}O_3^{ - 2} < {S_4}O_6^{ - 2} < {S_8} < SO_4^{ - 2} < {S_2}O_7^{ - 2}$
  • C
    ${S_4}O_6^{ - 2} < {S_2}O_3^{ - 2} < {S_8} < SO_4^{ - 2} < {S_2}O_7^{ - 2}$
  • D
    ${S_8} < {S_4}O_6^{ - 2} < {S_2}O_3^{ - 2} < SO_3^{ - 2} < {S_2}O_7^{ - 2}$
