Identifying the products of chemical reactions

Question 3

When solid potassium iodide, $KI\text{KI}$ , is reacted with concentrated sulfuric acid, $H2SO4\text{H}_2\text{SO}_4$ , a mixture of products is formed due to the strong reducing ability of the iodide ions. Which of the following options contains only the sulfur-containing products of this reaction that are formed via the reduction of sulfuric acid?

$SO2\text{SO}_2$ , $S\text{S}$ , and $H2S\text{H}_2\text{S}$

$KHSO4\text{KHSO}_4$ , $SO2\text{SO}_2$ , and $S\text{S}$

$SO2\text{SO}_2$ , $S\text{S}$ , and $I2\text{I}_2$

$HI\text{HI}$ , $SO2\text{SO}_2$ , and $H2S\text{H}_2\text{S}$
