(C) $HI$ cannot be prepared by the reaction of $KI$ with concentrated $H_2SO_4$ because $H_2SO_4$ acts as a strong oxidizing agent.Initially,the reaction produces $HI$:$KI + H_2SO_4 	o KHSO_4 + HI$However,the produced $HI$ is a strong reducing agent,and concentrated $H_2SO_4$ oxidizes $HI$ to $I_2$:$2HI + H_2SO_4 	o I_2 + SO_2 + 2H_2O$Therefore,$I_2$ is obtained instead of $HI$.
