Which electrodes can work even after being induced to large electric d

1.	Which electrodes can work even after being induced to large electric discharge such as defibrillation?(a) polarizing electrodes(b) magnetic electrodes(c) non-polarizing electrodes(d) electrolytic electrodesThis question was posed to me in a job interview.I would like to ask this question from Recording Electrodes in portion Bioelectric Signal and Electrodes of Biomedical Instrumentation
Answer» The correct option is (c) non-polarizing electrodes For explanation: Non-polarizing electrodes are designed to RAPIDLY dissipate any charge imbalance INDUCED by powerful ELECTRIC discharges such as a DEFIBRILLATION procedure. Rapid depolarization enables the immediate reappearance of bioelectric signals on the monitor after defibrillation. For this reason, non-polarizing electrodes have become the electrodes of choice for monitoring in the intensive CARE units and stress testing procedures.
