Assertion: If \[\lambda _{N{{a}^{+}}}^{0}+\lambda _{C{{l}^{-}}}^{0}\] are molar limiting conductivity of the sodium and chloride ions respectively, then the limiting molar conducting for sodium chloride is given by the equation: \[\wedge _{NaCl}^{0}=\lambda _{N{{a}^{+}}}^{0}+\lambda _{C{{l}^{-}}}^{0}\]. Reason: This is according to Kohlrausch law of independent migration of ions. Read the assertion and reason carefully to mark the correct option out of the options given below:

• A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
• B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
• C. If assertion is true but reason is false.
• D. If the assertion and reason both are false.
• E. If assertion is false but reason is true.
