(B) When potassium iodide $(KI)$ is heated with concentrated $H_2SO_4$,the initial reaction produces hydrogen iodide $(HI)$: $2KI + 2H_2SO_4 	ext{ (conc.)} 	o 2KHSO_4 + 2HI$ Since $HI$ is a strong reducing agent,it is further oxidized by concentrated $H_2SO_4$ to iodine $(I_2)$: $2HI + H_2SO_4 	ext{ (conc.)} 	o I_2 + SO_2 + 2H_2O$ Thus,the final product formed is iodine $(I_2)$.

Which of the following is formed when potassium iodide is heated with concentrated $H_2SO_4$?
