When solid potassium iodide, KI\text{KI}KI, is reacted with concentrated sulfuric acid, H2SO4\text{H}_2\text{SO}_4H2​SO4​, 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}_2SO2​, S\text{S}S, and H2S\text{H}_2\text{S}H2​S

KHSO4\text{KHSO}_4KHSO4​, SO2\text{SO}_2SO2​, and S\text{S}S

SO2\text{SO}_2SO2​, S\text{S}S, and I2\text{I}_2I2​

HI\text{HI}HI, SO2\text{SO}_2SO2​, and H2S\text{H}_2\text{S}H2​S
