How can the ionic conductivity of an unknown solution be determined?

Which of the following graphs represents the variation of molar conductance $(\Lambda_m)$ of an electrolyte with $\sqrt{C}$ for weak and strong electrolytes,respectively?

How does the conductivity of a strong electrolyte change upon dilution?

The equivalent conductance of $NaCl$, $HCl$, and $CH_{3}COONa$ at infinite dilution are $126.45$, $426.16$, and $91 \ \Omega^{-1} \ cm^{2} \ eq^{-1}$ respectively at $25^{\circ}C$. The equivalent conductance of acetic acid (at infinite dilution) would be:

Limiting molar conductivity of $NH_4OH$ [i.e.,$\Lambda ^o_{m(NH_4OH)}$] is equal to:
