The correct answer is a buffer

Explanation:

A buffer is an aqueous substance that resists change in pH when little quantity of a strong acid or strong base is added. A buffer is made up of a weak acid and its conjugate base or vice versa. Examples of buffer include Ammonium buffer, phosphate buffer and carbonate buffer.

A conjugate acid is a substance formed after receiving proton (from an acid) by a base.

A conjugate base is the substance formed/left when an acid loses a hydrogen ion after it dissociates.
