When solid sodium bromide, NaBr\text{NaBr}NaBr, is reacted with concentrated sulfuric acid, H2SO4\text{H}_2\text{SO}_4H2​SO4​, both acid-base and redox reactions take place.

Which of the following lists only products that are formed in these reactions?

NaHSO4\text{NaHSO}_4NaHSO4​, HBr\text{HBr}HBr, Br2\text{Br}_2Br2​, S\text{S}S, and H2O\text{H}_2\text{O}H2​O

NaHSO4\text{NaHSO}_4NaHSO4​ and HBr\text{HBr}HBr only

NaHSO4\text{NaHSO}_4NaHSO4​, HBr\text{HBr}HBr, Br2\text{Br}_2Br2​, SO2\text{SO}_2SO2​, and H2O\text{H}_2\text{O}H2​O

NaHSO4\text{NaHSO}_4NaHSO4​, HBr\text{HBr}HBr, Br2\text{Br}_2Br2​, H2S\text{H}_2\text{S}H2​S, and H2O\text{H}_2\text{O}H2​O
