Kohlrausch's law states that at

Kohlrausch's law states that at
  1. finite dilution, each ion makes definite contribution to equivalent conductance of an electrolyte, whatever be the nature of the other ion of the electrolyte.
  2. infinite dilution, each ion makes definite contribution to equivalent conductance of an electrolyte depending on the nature of the other ion of the electrolyte.
  3. infinite dilution, each ion makes definite contribution to conductance of an electrolyte whatever be the nature of the other ion of the electrolyte.
  4. infinite dilution, each ion makes definite contribution to equivalent conductance of an electrolyte, whatever be the nature of the other ion of the electrolyte.

Solution

According to Kohlrausch's law "at infinite dilution when the dissociation is complete, each ion makes a definite contribution towards equivalent conductivity of the electrolyte irrespective of the nature of the other ion with which it is associated. Or Equivalent conductivity of an electrolyte at infinite dilution is the sum of the equivalent conductivities of the cations and anion.
