Which of the following curves is in according with Freundlich adsorption isotherm?

According to the Freundlich adsorption isotherm xm=kp1nTaking log on both side log xm=1nlog p+log k                                                ↑ ↑ ↑ ↑Y =m x+ C On comparing it with equation of straight line and drawing the graph versus log xm we get a straight line with intercept log fr and slope of the straight line gives the value of 1n.
