Assertion : The molar conductance of weak electrolytes at infinite dilution is equal to sum of the molar conductances of cation and anion.
Reason : Kohlrausch's law is applicable to both strong and weak electrolytes.

A

If both assertion and reason are correct and reason is correct explanation for assertion.

B

If both assertion and reason are correct but reason is not correct explanation for assertion.

C

If assertion is correct but reason is incorrect.

D

If assertion and reason both are incorrect.
