Following figure shows dependence of molar conductance of two electrolytes on concentration, `wedge m^o` is the limiting molar conductivity.

The number of incorrect statement(s) from the following is ______
(A) `wedge m^o` for electrolyte A is obtained by extrapolation
(B) For electrolyte `B, wedge m` vs `sqrt(c)` graph is a straight line with intercept equal to `wedge m^o`
(C) At infinite dilution, the value of degree of dissociation approaches zero for electrolyte `B`.
(D) `wedge m^o` for any electrolyte `A` or `B` can be calculated using `lambda^(@)` for individual ions.
