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.
