Oxygen is divalent, but sulphur exhibits variable valency of 2, 4 and 6 because of the presence of d -orbitals in sulphur. In sulphur, the excitation of np -electrons to nd -sub-shell gives rise to increase in number of unpaired electrons. Option D is correct.
Carbon has a valency of 4, while sulfur has a valency of 6.
Out of the non-metals you listed, nitrogen (N) is the only one that does not exhibit variable valency. Zinc (Zn), copper (Cu), and iron (Fe) can exhibit variable valency in certain compounds.
The valency of sulfur in sulfuric acid is 6. Sulfuric acid has the chemical formula H2SO4, indicating that sulfur forms 6 bonds, with each oxygen atom contributing 2 bonds.
The valency of sulfur in the sulfite radical is +4. This is because sulfur has a usual oxidation state of +4 in the sulfite ion, which is SO3^2-.
The valency of sulfur in sulfuric acid (H2SO4) is +6. This means that sulfur can form up to 6 chemical bonds with other elements.
The valency of sulfur is 2-. The valency of sulfur is 2-. The valency of sulfur (S) is +2
The valency of sulfur in FeS2 is -2. This is because the overall charge of FeS2 is zero, and iron has a positive valency of +2. Therefore, sulfur must have a valency of -2 to balance the charge.
Carbon has a valency of 4, while sulfur has a valency of 6.

Variable valencies are the valencies which can change e.g. Fe (iron) can either have the valency of 2 (Fe II) or 3 (Fe III)
The valency of sulfur in hydrogen sulfide is 2. This means that sulfur in hydrogen sulfide forms two bonds with other elements or ions, such as hydrogen in this case.
Actually it is about the orbitals of valence shells of sulphur. Sulphur has atomic no. 16 and electronic configuration 1s2,2s2,2p6,3s2,3p4. Its outer most shell has s.p.d and f orbitals from which s and p have electrons and d and f are vacant. When 2 electrons from p are transferred to d, the valency becomes +2. When two more electrons from p are transfered to d, the valency becomes +4. When two left electrons from s are transferred to d, the valency becomes +6.
The valency of sulfur in sulfuric acid (H2SO4) is +6. Sulfur forms 4 covalent bonds (with oxygen atoms) and 2 ionic bonds (with hydrogen ions) in the compound.
6. The oxidation number of sulfur is +6. Another approach if you are not familiar with oxidation number is to draw Lewis dot diagrams for sulfate ion, these will have 2 double bonds and two single bonds (single bonds attaching negative charged oxygen atoms) and will show will show 6 bonds from sulfur.
