Solution

The correct option is D The Assertion is incorrect and the Reason is correct
A solution of a strong base and its salt with strong acid or a solution of weak acid its salt with strong base forms a buffer solution. Since water does not satisfy the above criteria, it does not act as a buffer.
A good buffer resists changes in $p H$ only in its buffer range.
Hence, the assertion is false but the reason is true.
