Solution

The correct option is B Both Assertion and Reason are correct but the Reason is not the correct explanation of the Assertion
Lewis base is the species which can donate a pair of electron.
Thus Assertion is correct.
The Ammonia is also Bronsted base as it accepts a proton to form ammonium ion.
Thus Reason also correct but it is not the correct explanation of the Assertion.
