Recent findings lend strong support to the theory that a

black hole lies at the center of the Milky Way and of many

of the 100 billion other galaxies estimated to exist in the

universe.

A.     that a black hole lies at the center of the Milky Way

and of

B.     that a black hole lies at the Milky Way’s center and

C.     that there is a black hole lying at the Milky Way’s

center an

D.     of a black hole lying at the Milky Way’s center and

E.      of a black hole that lies at the center of the Milky Way

and of

答案是A，可是A最后的of与谁平行呀，我觉得还是B更好一些，请NN指点

虽然排除法选了A，但不明白of的用法，请NN指教。

PS，我觉得milky way不好用‘s的形式吧，觉得还是the center of the Milky Way要好一些。

可是of没有平行对象是不是比's的问题更严重？

请NN们指教

这个of是和center后的of平行的吧，同时，center of Milky way比Milky way`s 要好很多。

貌似只能这么理解了
