Two students P and Q perform an experiment to verify Ohm’s law for a conductor with resistance R. They use a current source and a voltmeter with least counts of `0.1` mA and `0.1` mV, respectively. The plots of the variation of voltage drop (V) across R with current (I) for both are shown below The statement which is most likely to be correct is:A. P has only random error (s).B. Q has only systematic error (s).C. Q has both random and systematic errors.D. P has both random and systematic errors.
