The option S2- has the lowest oxidation number of sulphur.

The first option which is S8 has an oxidation number of zero because it is in elemental form and free state.

The oxidation number of sulphur in SO(3)2- is 4 .

The charge on the atom is -2, therefore the sum of the oxidation numbers of all the elements should be equal to -2.

x+3(-2)= -2

x = 4

The oxidation number of S in SO(4)2- is 6. The charge on the atom is -2, therefore the sum of the oxidation numbers of all the elements should be equal to -2.

x +4(-2) = -2

x = +6

The oxidation number of S in S(2)O(3)2- is 2.

The charge on the atom is -2, so sum of the oxidation numbers of all the elements should be equal to -2.

2x + 3(-2) = -2

2x = 4

x = 2

The oxidation number of S in S2- is -2 which is the lowest.
