- AWeak acid and its salt of strong base.
- BStrong acid + its salt of strong base.
- CWeak acid + its salt of weak base.
- DStrong base + its salts of strong acid.

Answer
- Weak acid and its salt of strong base.
Explanation:
A solution that resists change in pH value upon addition of a small amount of strong acid or base (less than 1 %) or when the solution is diluted is called buffer solution.
An acidic buffer solution consists of a solution of a weak acid and its salt with a strong base. while basic buffer solution consists of a mixture of a weak base and its salt with strong acid.
