The client in this context refers to a person or entity who is seeking electrification services. The most common type of electrodes used in general electrification projects are metal electrodes, which are typically made of copper, aluminum, or steel. Glass, plastic, and rubber electrodes are not suitable materials for general electrification as they are not conductive enough to carry electricity. Therefore, these options are incorrect and should not be chosen as they would not effectively hold or carry electricity.
