On Earth, among the surest indications of sunspot cycles are believed to be the rate that trees grow, as seen in the rings visible in the cross sections of their trunks.



A. On Earth, among the surest indications of sunspot cycles are believed to be the rate that trees grow

B. On Earth, among the surest indications of sunspot cycles are, it is believed, the rate of tree growth

C. On Earth, the rate at which trees grow is believed to be among the surest indications of sunspot cycles

D. Among the surest indications on Earth of sunspot cycles, believed to be the tree growth rate

E. Among the surest indications on Earth of sunspot cycles is believed to be the rate at which trees grow

为什么选E，E选项主语不是Indications嘛是复数，而它后面用了被动词is，不是矛盾吗？  C为什么不可以？

E的主语并不是indications而是the rate, 此句用的是一个倒装。
C中的the rate后面的at which错了， at which 是where的意思，不能修饰rate

是怎么样一个倒装，能帮我还原这句话吗，基础差所以还是看不明白
