Which statement about oxidation and reduction in a voltaic cell is true? a. both oxidation and reduction occur at the anode. b. both oxidation and reduction occur at the cathode. c. oxidation occurs at the anode and reduction occurs at the cathode. d. oxidation occurs at the cathode and reduction occurs at the anode.

C. Oxidation occurs at the anode and reduction occurs at the cathode.

Choice number third is the correct option for the given question

Explanation:

Copper and silver nitrate are the two components that form a voltaic cell. These are the two main ingredients which make the Redox reaction possible. The dog reaction that is taking place result in development of charge.

Since copper here is the anode in the reaction oxidation happens here by the solution is cathode this is where reduction takes place.
