Best answer
Right option is (b) False

The best I can explain: Ohm’s law is not a fundamental law of nature. Some reasons for the failure of ohm’s law are: Potential difference may vary non-linearly with the current ; The V-I relationship may be non-unique; The variation of current with potential difference may depend upon the sign of the potential difference applied.
