(B) The letters of the word $REPEAT$ are $\{A, E, E, P, R, T\}$.Arranging these letters in alphabetical order,we get: $A, E, E, P, R, T$.$1$. Words starting with $A$: $\frac{5!}{2!} = 60$.$2$. Words starting with $E$: $5! = 120$.$3$. Words starting with $P$: $\frac{5!}{2!} = 60$.$4$. Words starting with $RA$: $\frac{4!}{2!} = 12$.$5$. Words starting with $REA$: $3! = 6$.$6$. Words starting with $REE$: $3! = 6$.$7$. Words starting with $REPA$: $2! = 2$.$8$. The next word is $REPEAT$: $1$.Summing these up: $60 + 120 + 60 + 12 + 6 + 6 + 2 + 1 = 267$.Thus,the rank of the word $REPEAT$ is $267$.

If all the letters of the word $REPEAT$ are permuted in all possible ways and if the six-letter permutations thus formed are arranged in the dictionary order,then the rank of the word $REPEAT$ is:
