(C) The letters of the word $SACHIN$ are $A, C, H, I, N, S$ in alphabetical order.$1$. Words starting with $A$: $5! = 120$ words.$2$. Words starting with $C$: $5! = 120$ words.$3$. Words starting with $H$: $5! = 120$ words.$4$. Words starting with $I$: $5! = 120$ words.$5$. Words starting with $N$: $5! = 120$ words.Total words before words starting with $S$ are $5 	imes 120 = 600$.The next word in the dictionary order is the first word starting with $S$,which is $SACHIN$.Therefore,the serial number of $SACHIN$ is $600 + 1 = 601$.
