The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Electrolysis**: In electrolysis, an electric current is passed through an electrolyte, leading to the movement of ions. The electrolyte consists of cations (positively charged ions) and anions (negatively charged ions). 2. **Identifying Electrodes**: There are two electrodes in an electrolytic cell: - **Anode**: The positive electrode where anions are discharged. - **Cathode**: The negative electrode where cations are discharged. 3. **Cation Movement**: Cations, being positively charged, are attracted to the cathode (negative electrode). This is due to the opposite charges attracting each other. 4. **Discharge of Cations**: When cations reach the cathode, they gain electrons (reduction process) and are discharged. This process can lead to the formation of neutral atoms or molecules. 5. **Conclusion**: The discharge of a cation at the cathode is a fundamental process in electrolysis, where the cation is reduced by gaining electrons. ---
