Taq polymerase is a thermostable which states that it can even work at higher temperature. The main function of using this enzyme is that it is used to amplify the DNA which will help in producing ample amount of DNA sample.
The enzyme activity is temperature dependent. The denaturation and annealing steps of the PCR occurs at very high temperature.
Any other enzyme used at such an high temperature would have decreased the enzyme activity and the procedure would not be completed.
According to provided equation it is clear that Zn metal is oxidized from Zn⁰ into Zn²⁺ which means that Zn metal dissolves and forming Zn²⁺ solution so the correct answer is:
