Where are potentials picked up by patient electrodes taken to?(a) Lead

1.	Where are potentials picked up by patient electrodes taken to?(a) Lead Selector switch(b) Preamp(c) Power Amplifier(d) Instrumentational amplifierThe question was asked in an internship interview.My question is taken from System Concepts in section Patient Monitoring System of Biomedical Instrumentation
Answer» Right option is (a) LEAD Selector switch For explanation I would say: The potentials picked up by the patient ELECTRODES are TAKEN to the lead selector switch. In the lead selector, the electrodes are selected two by two ACCORDING to the lead PROGRAM.
