(B) The variation of molar conductivity $(\Lambda_m)$ with concentration $(C)$ for strong electrolytes like $KCl$ is given by the Kohlrausch equation: $\Lambda_m = \Lambda_m^{\circ} - A \sqrt{C}$.Here,$\Lambda_m^{\circ}$ is the molar conductivity at infinite dilution and $A$ is a constant.This equation follows the linear form $y = mx + c$,where $y = \Lambda_m$,$x = \sqrt{C}$,$m = -A$ (slope),and $c = \Lambda_m^{\circ}$ (intercept).Since the slope is negative $(-A)$,the plot of $\Lambda_m$ versus $\sqrt{C}$ is a straight line with a negative slope,indicating that $\Lambda_m$ decreases as $\sqrt{C}$ increases.

$LIST$-$I$ (Cell)	$LIST$-$II$ (Use/Property/Reaction)
$A$. Leclanche cell	$I$. Converts energy of combustion into electrical energy
$B$. Ni-Cd cell	$II$. Does not involve any ion in solution and is used in hearing aids
$C$. Fuel cell	$III$. Rechargeable
$D$. Mercury cell	$IV$. Reaction at anode $Zn \rightarrow Zn^{2+} + 2e^-$

Which one of the following is the correct plot of $\Lambda_m$ (in $S \ cm^2 \ mol^{-1}$) and $\sqrt{C}$ (in $mol^{1/2} \ L^{-1/2}$) for a $KCl$ solution? ($y=\Lambda_m$; $x=\sqrt{C}$)
