Anode is a positive pole and Cathode is a negative pole.

• A. Anode is a positive pole and Cathode is a negative pole
• B. Anode is a negative pole and Cathode is a positive pole
• C. Both electrodes are positive
• D. Both electrodes are negative

Answer: (A)

The key idea is how electrode polarity is defined depending on the cell type. The anode is the site of oxidation, and the cathode is the site of reduction. When a power source drives the reaction (an electrolytic cell), the external circuit pulls electrons away from the anode, so the anode becomes positively charged. Electrons are pushed toward the cathode, making it negatively charged. So, in this driven (electrolytic) context, the anode is a positive pole and the cathode is a negative pole. This contrasts with a galvanic cell, where the spontaneous flow makes the anode negative and the cathode positive. The statement aligns with the electrolytic convention, which is why it’s correct.
