Following are some facts about electrolytic conduction I : ${{\Lambda }_{m}}$ decreases with $\sqrt{C}$ due to increase in interionic attraction between ions II : For weak electrolytes, there is rapid increase in the degree of ionisation with dilution hence interionic attraction decreases and ${{\Lambda }_{m}}$ or ${{\Lambda }_{eq.}}$ increases rapidly in lower concentration range. III :$\Lambda _{m}^{\infty }$ can be obtained by extrapolation to $\sqrt{C}=0$. Correct statements are
