Unlike the other major planets, Pluto has a highly eccentric orbit, which is thus closer to the Sun than Neptune is for 20 years out of every 230-year cycle, even though it is commonly described as the remotest planet in the solar system.
(A) Pluto has a highly eccentric orbit, which is thus closer to the Sun than Neptune is
(B) Pluto has a highly eccentric orbit and is thus closer to the Sun than Neptune is
(C) Pluto's orbit is highly eccentric and is thus closer to the Sun than Neptune
(D) the orbit of Pluto is highly eccentric and thus closer to the Sun than Neptune
(E) the orbit of Pluto is highly eccentric, thus closer to the Sun than Neptune is
原文意思：不像其他星球，pluto有一个eccentric得轨道，pluto比neptune更接近太阳，即使pluto经常被认为是太阳系中最遥远的星球
题目分析：A中的which指orbit了，指代的东西不对（因为be closer的发起者和前面动词的发起者是一致的，如果发起者没有变，没有必要加which），杀。B用and连接，前后逻辑通顺，留着。C中的be closer发起者是pluto的orbit不是pluto了，发起者不对，杀。D和E中的be closer to的发起者全是orbit了，杀。
