The current-voltage plot provided indicates the relationship between the current (I) and voltage (V) for a certain electronic device. To determine the nature of this device, we need to analyze the options given.

Option 1 states that the device is a semiconductor. Semiconductors are materials whose electrical conductivity lies between that of conductors and insulators. In the plot, if the relationship between current and voltage is linear (i.e., a straight line passing through the origin), it would suggest that the device is a semiconductor. However, the plot provided does not display a linear relationship, so option 1 can be eliminated.

Option 2 suggests that the device is a conductor which obeys Ohm`s law. According to Ohm`s law, the current passing through a conductor is directly proportional to the voltage applied across it. Looking at the plot, the relationship between current and voltage is indeed linear, indicating that the device follows Ohm`s law. Hence, option 2 is correct.

Option 3 proposes that the device is a superconductor. Superconductors are materials that exhibit zero electrical resistance at extremely low temperatures. The plot does not provide any evidence of zero resistance, so option 3 can be ruled out.

Option 4 claims that the device
