A is wrong as it is wordy and unidiomatic as "to be the rate that tree grows"is not souding correct
B is wrong as same are is wrong the phrase "it is believed" modifies the meaning of the sentence and placement of it is wrong
c is wrong as the later part of the sentence is the modiier for the tree growth so it should be as close as posible to the later part
d setting believed to be by comma gives a wrong meaning
E is right as the insertion of verb is gives the right meaning to the sentence

apurva - you make a good point as to why C is wrong. However, I am still a little unclear on E. Could you explain further?

Thanks

i think the subject is "among the surest indications" which is a phrase and hence singular.

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

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

it is wrong to say that either "Among the surest indications" or "Earth" is the subject of the sentence.

This is a case of inversion and the subject is "the rate at which trees grow". the sentence can be read as: "The rate at which trees grow is believed to be among the surest indications on Earth of sunspot cycles, as seen in the rings visible in the cross sections of their trunks".

For the first one the non-underlined part 'as seen in the rings visible in the cross sections of the tree' was the key
for me to look for answer and only think that portion could modify was 'indications of sunspot cycles'. So, I pick C

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

I was between C and D. C seemed to be a simpler one. So, I pick C again.
