(B) The word $COMMITTEE$ contains $9$ letters in total.The frequencies of the letters are as follows:$C$ appears $2$ times,$O$ appears $2$ times,$M$ appears $2$ times,$I$ appears $1$ time,$T$ appears $2$ times,$E$ appears $1$ time.Total number of arrangements = $\frac{n!}{n_1! n_2! n_3! ... n_k!}$Here,$n = 9$,$n_1 = 2$ (for $C$),$n_2 = 2$ (for $O$),$n_3 = 2$ (for $M$),$n_4 = 2$ (for $T$).Total arrangements = $\frac{9!}{2! 2! 2! 2!} = \frac{9!}{(2!)^4}$.Since the provided options do not match the calculated result $\frac{9!}{(2!)^4}$,we re-evaluate the word $COMMITTEE$: $C(2), O(1), M(2), I(1), T(2), E(2)$. Wait,$COMMITTEE$ has $C=2, O=1, M=2, I=1, T=2, E=2$. Total letters = $9$. Arrangements = $\frac{9!}{2! 2! 2! 2!} = \frac{9!}{16}$.Given the options,if we assume the word was $COMMITEE$ (missing one $T$),it would be $\frac{8!}{2!2!2!}$.However,for $COMMITTEE$,the correct formula is $\frac{9!}{(2!)^4}$. Given the options provided,option $B$ is the closest intended answer structure.
