The plot of molar conductance vs sqrt(C) in strong electrolyte , is

For strong electrolytes the values of molar conductivities at infinite dilution are given below {:("Electrolyte",^^_(m)^(@) (Sm^(2 mol^(-1))),(BaCl_(2),280 xx 10^(-4)),(NaCl,126.5 xx 10^(-4)),(NaOH,48 xx 10^(-4)):} The molar conductance at infinite dilution for Ba(OH)_(2) is

Statement: For a weak electrolyte, the plot of molar conductivity (Lambda_(m)) against sqrt(C )(C is concentration in mol litre^(-1)) is nearly linear. Explanation: The molar conductivity at infinite dilution (Lambda_(m)) for an electrolyte can be considered equal to the sum of the limiting molar conductivities of the individual ions.

For a dilute solution of a strong electrolyte, the variation of molar conductivity with concentration is given by

Above plot represents the variation of molar conductance against sqrtC (where C = molar concentration of the electrolyte) . Select the correct option among following .
