The molecule is composed of Sulfur and Oxygen, which are both elements with high electronegativities. As a result, this is a covalent bond, as they are both nonmetals. Since Sulfur has a partially positive charge, and Oxygen has a partially negative charge, it appears that the substance is polar, meaning that there are different charges within the atom. Of the answer choices, Dipole-Dipole forces are the only ones that involve polar substances, and they different charges, especially since there is no hydrogen indicating a hydrogen bond, and London forces contain nonpolar substances with an overall charge of the molecule.
