Identify the redox reaction among the following: 

To respond, keep in mind that gaining an electron results in reduction, whereas losing an electron results in oxidation. A redox reaction is one that involves simultaneous reduction and both oxidation and reduction.

To respond to this query, it is necessary to comprehend what a redox reaction is.
The term "redox reaction," which stands for a reduction-oxidation reaction, refers to a process in which oxidation and reduction occur concurrently. The oxidation number of the species that are reacting changes during a redox reaction, indicating the transfer of electrons.

Let's now examine the reactions that were presented to us and decide whether or not they were redox reactions.
First, we neutralise the acid and base. A neutral solution is produced in this reaction between an acid and a base. There aren't any extra hydrogen ions or hydroxide ions in the solution. Based on the relative strengths of the acid and base, there are four different types of acid-base neutralisation reactions that can occur. However, no electrons are transferred and the reactant species' oxidation levels do not change in a neutralisation reaction. This means that it is not a redox reaction.

Precipitation responses follow. When two soluble salts are combined in a solution, an insoluble precipitate results from this process. An element's number of electrons, or oxidation state, must change for a reaction to be redox. Precipitation reactions are not redox reactions since there is no change in the oxidation states.
Finally, there are reactions that involve metal displacement. The more reactive metal replaces the less reactive metal in its solution in a displacement reaction.

${\stackrel{0}{Z}}^0\left(s\right)+\stackrel{+2}{\mathrm{Cu}}{\stackrel{+6}{S}{\mathrm{O}}_4^{-2}}^2\left(aq\right)\to {}_Z{}^{+2}+\stackrel{+6}{S}{\stackrel{O}{O}}_4^2\left(aq\right)+\stackrel{0}{Cu}\left(s\right)$

Here, we can observe that the oxidation states of copper and zinc move from +2 to 0 and 0 to +2, respectively. As both oxidation and reduction are occurring at the same time, this is a redox process.

Therefore, the correct answer is option (C) metal displacement reaction.
