Answer

A

Work Step by Step

Sulfur and oxygen are in group 16, therefore they have 6 valence electrons each for a total of 26, including the two gained to have a 2- charge. For a single bond between each oxygen and the sulfur, 6 are used. To get to eight valence electrons, each oxygen must have 6 more, so another 18 are used. The last two are assigned to the sulfur.
