Assertion $\displaystyle (A)$ : Limiting molar conductivity $\displaystyle \left(\mathbf{\Lambda}_{\mathrm{m}}^{\circ}\right)$ is obtained by the extrapolation of the $\displaystyle \mathbf{\Lambda}_{\mathrm{m}}$ versus $\displaystyle \mathrm{C}^{1 / 2}$ curve of strong electrolyte. Reason $\displaystyle (R): \quad \mathbf{\Lambda}_{\mathrm{m}}^{\circ}$ for weak electrolytes is obtained by using Kohlrausch's law.
