Following figure shows dependence of molar conductance of two electrolytes on concentration. $\displaystyle \Lambda \stackrel{\circ}{m}$ is the limiting molar conductivity.

The number of incorrect statement(s) from the following is $\displaystyle \_\_\_\_$

(A)

$\displaystyle \Lambda \stackrel{\circ}{m}$ for electrolyte A is obtained by extrapolation

(B)

For electrolyte $\displaystyle \mathrm{B}, \Lambda m$ vs $\displaystyle \sqrt{c}$ graph is a straight line with intercept equal to $\displaystyle \Lambda \stackrel{\circ}{m}$

(C)

At infinite dilution, the value of degree of dissociation approaches zero for electrolyte B.

(D)

$\displaystyle \Lambda \stackrel{\circ}{m}$ for any electrolyte A or B can be calculated using $\displaystyle \lambda^{\circ}$ for individual ions
