(B) The Freundlich adsorption isotherm is given by the equation: $\frac{x}{m} = K P^{\frac{1}{n}}$Taking the logarithm on both sides,we get: $\log \frac{x}{m} = \frac{1}{n} \log P + \log K$This is a linear equation of the form $y = mx + c$,where the plot of $\log \frac{x}{m}$ versus $\log P$ should be a straight line with a slope of $\frac{1}{n}$ and an intercept of $\log K$.Analyzing the given curves:$1$. The first curve $(a)$ is a non-linear curve of $\log \frac{x}{m}$ vs $\log P$,which is incorrect.$2$. The second curve $(b)$ is a linear plot of $\log \frac{x}{m}$ vs $P$,which is incorrect.$3$. The third curve $(c)$ is a linear plot of $\log \frac{x}{m}$ vs $P$,which is incorrect.$4$. The fourth curve $(d)$ is a linear plot of $\log \frac{x}{m}$ vs $\log P$ with a positive intercept,which is correct.Therefore,there are $3$ curves that are not in accordance with the Freundlich adsorption isotherm.

Among the following,the number of curves not in accordance with the Freundlich adsorption isotherm is:
