(A) buffer solution is a mixture that resists changes in $pH$ upon the addition of small amounts of acid or base. It typically consists of a weak base and its salt,or a weak acid and its salt.In option $A$,mixing equal volumes of $0.2 \, M \ NH_{4}OH$ (weak base) and $0.1 \, M \ HCl$ (strong acid) results in a reaction where $0.1 \, M$ of $NH_{4}OH$ reacts with $0.1 \, M$ of $HCl$ to form $0.1 \, M \ NH_{4}Cl$ (salt). The remaining concentration of $NH_{4}OH$ is $0.1 \, M$. Since the final mixture contains both the weak base $(NH_{4}OH)$ and its salt $(NH_{4}Cl)$,it forms a basic buffer solution.
