The dissociation of a weak electrolyte increases on dilution.

In the plot of molar conductivity$\left({\wedge }_{\mathrm{m}}\right)$  vs square root of concentration $\left({\mathrm{c}}^{1/2}\right)$, following curves are obtained for two electrolytes A and B :

Answer the following :

What happens on extrapolation of ${\wedge }_{\mathrm{m}}$ to concentration approaching zero for electrolytes A and B ?

Given below are two statements:

Statement I: For $\mathrm{KI}$, molar conductivity increases steeply with dilution.

Statement II: For carbonic acid, molar conductivity increases slowly with dilution. In the light of the above statements, choose the correct answer from the options given below
