Given below are 2 statements: Assertion and Reason. Choose the correct option.
Assertion: When Molar conductivity for a strong electrolyte is plotted versus $ \sqrt{C} \, (\text{mol/L})^{1/2} $, a straight line is obtained with intercept equal to Molar conductivity at infinite dilution for the electrolyte and slope equal to $ -A $. All electrolytes of a given type have the same $ A $ value.
Reason: At infinite dilution, strong electrolytes of the same type will have different numbers of ions due to incomplete dissociation.
