Quasars, at billions of light-years from Earth the most distant observable objects in the universe, believed to be the cores of galaxies in an early stage of development.

(A)believed to be
(B)are believed to be
(C)some believe them to be
(D)some believe they are
(E)it is believed that they are

答案是B，我没有异议。但是题目中的at billions of light-years from Earth the most distant observable objects in the universe,是不是主语的同位语啊？可不可以改成  the most distant observable objects in the universe at billions of light-years from Earth ？

是对名词的解释说明，不一定是同位语。LZ这样改，不能说不对，只能说把状语并列后很别扭。

谢谢。还是有点不明白这句话在整句话里做什么成分，它也不是一个完整的句子？

可以这样说就是一个同位语。但是如果放在universe之后有修饰universe之疑，所以提前放在句首，同时也避免修饰部分的头重脚轻。
如果加上that are就不会有模糊修饰嫌疑。
the most distant observable objects in the universe (that are) at billions of light-years from Earth
