(C) The degree of unsaturation (DoU) is calculated by counting the number of rings and $\pi$ bonds in the structure.$1$. Rings: There are $3$ rings (one benzene ring and two saturated six-membered rings).$2$. $\pi$ bonds: There is $1$ triple bond ($2 \pi$ bonds),$2$ double bonds ($2 \pi$ bonds),and $1$ carbonyl group ($1 \pi$ bond).Total $\pi$ bonds $= 2 + 2 + 1 = 5$.Total DoU $= 	ext{Number of rings} + 	ext{Number of } \pi 	ext{ bonds} = 3 + 5 = 8$.Wait,re-evaluating the structure: The benzene ring contributes $4$ ($1$ ring + $3$ $\pi$ bonds). The other two rings contribute $2$. The triple bond contributes $2$. The double bond contributes $1$. The carbonyl group contributes $1$. Total $= 4 + 2 + 2 + 1 + 1 = 10$.Therefore,the correct option is $C$.
