In the redox reaction MnO_2 + 4HCl → MnCl_2 + 2H_2O + Cl_2

In the redox reaction

`"MnO"_2` + 4HCl → `"MnCl"_2` + `"2H"_2"O"` + `"Cl"_2`

A. `"MnO"_2` is reduced to `"MnCl"_2`& HCl is oxidized to `"H"_2"O"`
B. `"MnO"_2` is reduced to `"MnCl"_2`& HCl is oxidized to `"Cl"_2`
C. `"MnO"_2` is oxidized to `"MnCl"_2` & HCl is reduced to `"Cl"_2`
D. `"MnO"_2` is oxidized to `"MnCl"_2` & HCl is reduced to `"H"_2"O"`

Correct answer is option B. MnO_2 is reduced to MnCl_2 & HCl is oxidized to Cl2. Explanation: In the redox reaction of MnO_2 + 4HCl → MnCl_2 + 2H_2O + Cl_2 happens that, MnO_2 is reduced to MnCl_2 & HCl is oxidized to Cl2.
