A good buffer system consists of a weak acid and its conjugate base or a weak base and its conjugate acid. In option A, HC₂H₃O₂ is the weak acid and its conjugate base is LiC₂H₃O₂, making it a good buffer system. The other options do not have a weak acid and its conjugate base or a weak base and its conjugate acid present.
