Buffer solution is a mixture of weak acid and its conjugate base formed with strong acid.
Or weak base and it's conjugate acid formed with strong acid
Hence among the given, option D . It is a mixture of weak acid (HCN) and it's conjugate base NaCN.
Option A has both strong acid (HNO3) strong base NaOH.
B ha strong acid HNO3 & strong base LiOH.
D has both are strong.
