Select the correct statement for ${\mathrm{\Lambda }}_{\mathrm{m}}={\mathrm{\Lambda }}_{\mathrm{m}}^{\circ }-{\mathrm{AC}}^{1/2}$.

For strong electrolytes ${\mathrm{\Lambda }}_{\mathrm{m}}={\mathrm{\Lambda }}_{\mathrm{m}}^{\circ }-{\mathrm{AC}}^{1/2}$
If we plot ${\mathrm{\Lambda }}_{\mathrm{m}}^{ }$ against ${\mathrm{C}}^{1/2}$,we obtain straight line with intercept equal to  and slope is equal to -A. The constant A depends on the type of electrolyte. i.e. charges on cation and anion produced on dissociation of electrolyte.
