C)only III
D)II and III

Question

Quizplus · Accepted Answer

Both galvanic cells and voltaic cells involve spontaneous chemical reactions generating an electric current. The term "galvanic cell" is generally used for cells that use spontaneous redox reactions to generate electrical energy. "Voltaic cell" is a more general term that can refer to any type of electrochemical cell that generates an electric current through spontaneous chemical reactions. "Electrolytic cell" is a type of cell that drives non-spontaneous redox reactions using an external voltage source, and is not the appropriate term for a cell in which a spontaneous reaction generates current.
