Answer = A

Explanation:

As buffers are solutions which resist the change in pH when a small amount of acid or base (often strong) are added to it.

Reason for selecting option A is that, Buffer solution has a specific capacity to resist the change in pH both either acid or base is added to it and maintains its effectiveness. Its capacity is up to a particular level, when this level is crossed then buffer solution looses its capacity and becomes ineffective.
