$A$ weak acid $+$ its salt with a strong base

(D) An acidic buffer is prepared by mixing a weak acid and its salt with a strong base. Such buffers are typically used to maintain a $pH$ in the acidic range,specifically $pH$ $4 - 5$. Therefore,the correct mixture is a weak acid and its salt with a strong base.
