उत्तर

CH3COOH + CH3COONa in water

Explanation:

A buffer solution is a water-based mixture of a weak acid and its conjugate base. It could potentially be a combination of a weak base and its conjugate base.

In the given, only option C has weak acid CH3​COOH and its conjugate base CH3​COONa

Option A has a strong base and its conjugate base.

Options D and B are not buffer solutions as they contain strong acids HCl.
