Final answer:

The compound S2O3 is named disulfur trioxide, reflecting the presence of two sulfur atoms and three oxygen atoms. The option (B) is correct.

Step-by-step explanation:

The name of the compound S2O3 is disulfur trioxide. This name is derived from the fact there are two sulfur atoms (di-) and three oxygen atoms (-trioxide) in the molecule. While considering the nomenclature of sulfur oxygen compounds such as sulfur dioxide (SO2) and sulfur trioxide (SO3), each compound is given a unique name based on its distinct molecular geometry and number of oxygen atoms.

Therefore, the S2O3 molecule, which is not as common as sulfur dioxide or sulfur trioxide, combines the prefix for two sulfur atoms (di-) with the stem 'ox-' and the suffix indicating three oxygen atoms (-trioxide), resulting in the proper name disulfur trioxide. Therefore, option (B) is correct.
