Choose the correct answer from the options given below:
$(A)$ $\Lambda \stackrel{0}{ m }$ for electrolyte $A$ is obtained by extrapolation
$(B)$ For electrolyte B, vx $\Lambda m$ vs $\sqrt{ c }$ graph is a straight line with intercept equal to $\Lambda \stackrel{0}{ m }$
$(C)$ At infinite dilution, the value of degree of dissociation approach zero for electrolyte $B$.
$(D)$ $\Lambda \stackrel{0}{ m }$ for any electrolyte $A$ or $B$ can be calculated using $\lambda^{\circ}$ for individual ions.
