Answer: Electrolytic cell.
- A Galvanic cell
- B Voltaic cell
- C Electrolytic cell
- D Fuel cell
Correct answer: C. Electrolytic cell
Explanation: An electrolytic cell uses external electrical energy to drive a non-spontaneous chemical reaction.
In a Daniell cell, electrons flow externally from the zinc anode (oxidation) through the voltmeter to the copper cathode (reduction), while the salt bridge completes the circuit.
