Which of following is a wrong statement?

If concentration of solution decreases then conductance decreases

Concentration decreases,$\lambda_m$ increases for strong electrolytes

Concentration decreases,$\lambda_m\;$increases for weak electrolytes

$\lambda_m=\lambda_m^{\infty}-b\sqrt{C}$ applicable for both strong & weak electrolyte

Can you answer this question?

If concentration $\uparrow$ ,no of ions per unit volume $\downarrow$,so conductance $\downarrow$
If concentration $\uparrow$ ,since mole is fixed.So volume $\uparrow$,so distance between ions $\uparrow$ and mobility of ions $\uparrow$,so conductance $\uparrow$
$\Rightarrow \lambda_m=\lambda_m^{\infty}-b\sqrt{C}\;\text{applicable for both strong & weak electrolyte}$
Hence (d) is the correct answer.
