1. Given $\mathbf{Z}$ is the set of integers, the set $A=\{x|| x-3 |<\pi, x \in \mathbf{Z}\}, B=\left\{x \mid x^{2}-11 x+5<0\right.$, $x \in \mathbf{Z}\}, C=\left\{x|| 2 x^{2}-11 x+10|\geqslant| 3 x-2 \mid, x \in \mathbf{Z}\right\}, \bar{C}$ is the complement of $C$ in $\mathbf{Z}$, then the number of proper subsets of $A \cap B \cap \bar{C}$ is
A. 7
B. 8
C. 15
D. 16
