Solution

The correct option is A
Redox

The reaction which involves both oxidation and reduction are called redox (oxidation-reduction) reactions. Redox reactions include all the chemical reactions in which atoms undergo a change in their oxidation state. In general, redox reactions involve the transfer of electrons between species.The term "redox" comes from two concepts involved with electron transfer: reduction and oxidation.

$M n O_{2} + 4 H C l \to M n C l_{2} + 2 H_{2} O + C l_{2}$ is a redox reaction.
