Magnitude of voltage picked up is denoted ase = CHVd, where C is _____

1.	Magnitude of voltage picked up is denoted ase = CHVd, where C is __________(a) velocity of blood flow(b) strength of magnetic field(c) diameter of blood vessel(d) constant of proportionalityThe question was posed to me during an interview for a job.This intriguing question originated from Application of Telemedicine in chapter Telemedicine Technology of Biomedical Instrumentation
Answer» The correct option is (c) diameter of BLOOD vessel Easiest explanation: The magnitude of the voltage picked up is directly PROPORTIONAL to the strength of the magnetic FIELD, the diameter of the blood vessel and the VELOCITY of blood flow, i.e. e = CHVd, where e = induced voltage, H = strength of the magnetic field, V = velocity of blood flow, d = diameter of the blood vessel and C = constant of proportionality.
