$3.0 、 I$ are the circumcenter and incenter of acute $\triangle A B C$, respectively. $O^{\prime} 、 I^{\prime}$ are the reflections of $O 、 I$ over $B C$, respectively. It is known that $A 、 B 、 O^{\prime} 、 C$ are concyclic. Then, the position of point $I^{\prime}$ is ( ).
(A) outside $\odot O$
(B) inside $\odot O$
(C) on $\odot O$
(D) cannot be determined
