Step 1: Concept
A Galvanic (Voltaic) cell converts chemical energy into electrical energy using a spontaneous reaction.
Step 2: Meaning
In a Galvanic cell, electrons are released at the anode (oxidation), making it the negative terminal. Electrons are consumed at the cathode (reduction), making it the positive terminal.
Step 3: Analysis
Statement (C) incorrectly identifies the polarities; it describes an electrolytic cell, not a galvanic cell.
Step 4: Conclusion
The incorrect statement is (C).
Final Answer: (C)
