A current can be made to flow in a wire by all of the given options. If a wire is connected to a battery, the potential difference between the ends of the wire will create an electric field, which will result in the movement of electrons and the flow of current. Similarly, if a wire is moving near a magnet or a magnet is moving near to it, the changing magnetic field will induce an electric field, which will result in the movement of electron and the flow of current. Therefore, all options (A), (B), and (C) are correct.
