Electricity in voltaic cell is produced due to_________________?
Correct answer: D. both B & C
- A. neutralization
- B. oxidation
- C. reduction
- D. both B & C
Explanation
A voltaic cell produces electricity through a coupled redox process: oxidation occurs at the anode and reduction occurs at the cathode. Choosing only oxidation or only reduction ignores that both half-reactions must occur together for electrons to flow.

About Redox Reactions
Redox reactions involve oxidation and reduction occurring together, with electrons transferred between species or oxidation numbers changing. The topic covers assigning oxidation states, identifying oxidizing and reducing agents, balancing redox equations by oxidation number or half-reaction methods, and connecting chemical changes with galvanic and electrolytic cells.
