# Molar conductivity is defined as (where $k$ is the conductivity and $c$ is the molar concentration of electrolyte.)

$\begin{array}{1 1}kc\\kc^2\\k/c^2\\k/c\end{array}$

Answer : $k/c$
Molar conductivity is defined as the conductivity of an electrolyte solution divided by the molar concentration of the electrolyte, and so measures the efficiency with which a given electrolyte conducts electricity in solution.
Molar conductivity is defined as $\Lambda _m=k/c$
