Identifying the products of chemical reactions

Question 2

A student adds concentrated sulfuric acid to solid sodium iodide in a boiling tube. A vigorous reaction occurs, producing a mixture of gases, a solid residue, and a dark purple vapor. Which of the following lists only the reduction products of sulfuric acid formed in this reaction?

$SO2(g)\text{SO}_2(g)$ , $S(s)\text{S}(s)$ , and $H2S(g)\text{H}_2\text{S}(g)$

$HI(g)\text{HI}(g)$ , $SO2(g)\text{SO}_2(g)$ , $S(s)\text{S}(s)$ , and $H2S(g)\text{H}_2\text{S}(g)$

$I2(g)\text{I}_2(g)$ , $SO2(g)\text{SO}_2(g)$ , $S(s)\text{S}(s)$ , and $H2S(g)\text{H}_2\text{S}(g)$

$SO2(g)\text{SO}_2(g)$ and $S(s)\text{S}(s)$ only
