Detailed Solution

On dilution as volume of solution increases. Thus, the number of ions per ml decreases and hence conductivity decreases. Molar conductivity is defined for 1 mole of ions. Thus on dilution, ions get more apart and mobility of ions increases which leads to increase in molar conductivity of the solution.
