(A) For an ohmic resistance,the potential difference $V$ is directly proportional to the current $I$ flowing through it,according to Ohm's Law.This is expressed as $V \propto I$,which can be written as $V = RI$,where $R$ is the resistance and is a constant.The equation $V = RI$ represents a straight line passing through the origin in a $V$-$I$ graph,where the slope of the line is equal to the resistance $R$.Therefore,the graph that represents an ohmic resistance is a straight line passing through the origin.
