(A) $HCl$ is a strong acid,so its $pH$ is very low (approx $1$).$NH_4Cl$ is a salt of a strong acid $(HCl)$ and a weak base $(NH_4OH)$,making it acidic $(pH $NaCl$ is a salt of a strong acid $(HCl)$ and a strong base $(NaOH)$,making it neutral $(pH = 7)$.$NaCN$ is a salt of a weak acid $(HCN)$ and a strong base $(NaOH)$,making it basic $(pH > 7)$.Therefore,the correct order of $pH$ is: $HCl < NH_4Cl < NaCl < NaCN$.

The correct order of $pH$ for $0.1 \ M$ solutions is:
