0.10 M HCN and 0.10 M LiCN solution is a good buffer system among the given options.

A buffer system consists of a weak acid and its conjugate base. The main function of the buffer solution is to resist the change in pH. Among the given options the first option has HCN as acid and LiCN as the conjugate base. In the second option, HNO₃ is used as an acid, as HNO3 is a strong acid so it is not suitable for a good buffer solution. In the third option, HCl is used as an acid which is also a strong acid so not suitable for a buffer solution. In the last option again HNO₃ is used as an acid which is a strong acid. So the best option is the 1st one having HCN, which is a weak acid.
