Understand the basic definitions: A voltaic cell (or galvanic cell) is an electrochemical cell that derives electrical energy from spontaneous redox reactions taking place within the cell. An electrolytic cell, on the other hand, uses electrical energy to drive a non-spontaneous chemical reaction.

Analyze statement I: 'The flow of electrons is spontaneous.' In a voltaic cell, the redox reaction is spontaneous, meaning it occurs naturally without external energy. In an electrolytic cell, the reaction is non-spontaneous and requires an external power source. Therefore, this statement is true for a voltaic cell and false for an electrolytic cell.

Analyze statement II: 'Oxidation occurs at the anode.' In both voltaic and electrolytic cells, oxidation occurs at the anode. This is a fundamental principle of electrochemistry, so this statement is true for both types of cells.

Analyze statement III: 'Electrons flow from the anode to the cathode.' In both voltaic and electrolytic cells, electrons flow from the anode to the cathode. This is a consistent behavior in electrochemical cells, so this statement is true for both types of cells.

Determine the correct answer: Based on the analysis, only statement I is true for a voltaic cell and false for an electrolytic cell. Therefore, the correct answer is 'Only I.'
