ohms law states that the flow of eletric current in a *metalic* conductor is directly proportional to the potential difference applied across the end, provide that the physical condition are kept constant..... A is correct

A diode is made up of semiconductors. Ohm's law says the current passing through a conductor is proportional to the potential difference across the conductor. In the case of a diode, the current through it does not linearly depend on the potential difference. Hence, diodes do not obey Ohm's law.
so the correct option is all metals
