(B) The correct answer is $(B)$.$Cl^-$ ions have a weak reducing nature and can only be oxidized by strong oxidizing agents.$(A)$ $2HCl + PbO_2 	o PbO + Cl_2 \uparrow + H_2O$ (Oxidation occurs)$(B)$ $HCl + 	ext{conc. } H_2SO_4 	o 	ext{No reaction}$ (Concentrated $H_2SO_4$ acts as a dehydrating agent but does not oxidize $HCl$ to $Cl_2$)$(C)$ $4HCl + MnO_2 	o MnCl_2 + Cl_2 \uparrow + 2H_2O$ (Oxidation occurs)$(D)$ $14HCl + K_2Cr_2O_7 	o 2CrCl_3 + 2KCl + 3Cl_2 \uparrow + 7H_2O$ (Oxidation occurs)
