Solution

The correct option is B Non-ohmic conductors
According to ohm's law,
$I = \frac{V}{R}$ . . . . . .(1)
The electric current is proportional to the voltage.
$I \propto V$
It gives linear relationship. The graph between the electric current and voltage is straight line passing through the origin.
The $I - V$ characteristics shown in the figure is Non- ohmic conductor.
The correct option is B.
