(9)已知 $\mathrm{O}, \mathrm{N}, \mathrm{P}$ 在 $\triangle A B C$ 所在平面内,且 $|\overline{O A}|=|\overline{O B}|=|\overline{O C}|, \overline{N A}+\overline{N B}+\overline{N C}=0$ ,且 $\overline{P A} \bullet \overline{P B}=\overline{P B} \bullet \overline{P C}=\overline{P C} \bullet \overline{P A}$ ,则点 $\mathrm{O}, \mathrm{N}, \mathrm{P}$ 依次是 $\triangle A B C$ 的
(A)重心 外心 垂心(B)重心 外心 内心
(C)外心 重心 垂心
