Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Effective nuclear charge of inert gases is minimum.
Second IP of alkali metals is maximum in the period as it involves removal of electron from stable inert gas configuration.
Thus, Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
