Calculate the degree of dissociation $(\propto )$ of acetic acid, if its molar conductivity $\left({\mathrm{Ʌ}}_{\mathrm{m}}\right)$ is $39.05 \mathrm{S} {\mathrm{cm}}^2 {\mathrm{mol}}^{-1}$. 

Given: $\mathrm{\lambda }{°}_{\left({\mathrm{H}}^{+}\right)}=349.6 \mathrm{S} {\mathrm{cm}}^2 {\mathrm{mol}}^{-1}$ and $\mathrm{\lambda }{°}_{\left({\mathrm{CH}}_3{\mathrm{COO}}^{-}\right)}=40.9 \mathrm{S} {\mathrm{cm}}^2 {\mathrm{mol}}^{-1}$.

Following figure shows dependence of molar conductance of two electrolytes on concentration. ${\mathrm{\Lambda }}_{\mathrm{m}}^0$ is the limiting molar conductivity.

The number of Incorrect statement(s) from the following is _____

(A) ${\mathrm{\Lambda }}_{\mathrm{m}}^0$ for electrolyte $\mathrm{A}$ is obtained by extrapolation
(B) For electrolyte $\mathrm{B}, {\mathrm{\Lambda }}_{\mathrm{m}} \mathrm{Vs} \sqrt{\mathrm{c}}$  graph is a straight line with intercept equal to ${\mathrm{\Lambda }}_{\mathrm{m}}^0$
(C) At infinite dilution, the value of degree of dissociation approach zero for electrolyte $\mathrm{B}$.
(D) ${\mathrm{\Lambda }}_{\mathrm{m}}$ for any electrolyte $\mathrm{A}$ or $\mathrm{B}$ can be calculated using $\mathrm{\lambda }°$ for individual ions.

The electronic conductivity does not depend on
