Sagot :

The oxidation -reduction reaction among the given reactions is option b where, copper oxidizes and silver metal reduces.

What is redox reaction?

A redox reaction is a type of reaction in  which a reactant species reduces whereas, another group oxidizes. The species which is oxidized is called oxidant and the one which is reduced is called the reductant.

Among the given reactions, the reaction between metallic copper with silver nitrate producing copper nitrate and silver metal is a redox reaction. Here, the copper metal gets oxidized to Cu²⁺ state by losing two electrons.

Silver nitrate gains two electrons forming the reduced state of silver metal and the metal deposits in the solution. Hence, option b is correct.
