I will go for E. the only thing i know is that ESTIMATED AT is not idiomatic and it should be Estimated to be which is not used in any of the choices. Only E makes a bit sense with It is estimated that...

The adverbial phrase " By the end of 21st century" at the beginning of the sentence reduces the ambiguity.

I prefer C to E....

will go with E...estimated at is unidiomatic...more over C can not be the rt answer as it gives the impression that the estimation it self was done at the end of the 21st century..

'Estimated at' is unidiomatic'. 'Estimated to be' is better though 'to be' is usually incorrect on GMAT.

Leaves only E.

I go with C.
I think E is incorrect because we can't write 'cost to' has to be 'cost of'

I am going with C.

E is too wordy... the cost to the average individual can easily be replaced by the average individual's cost.

According to Manhattan GMAT SC, 'estimated to be' is supposed to be idiomatic, but I am not too positive about that.

If anything E gives the impression that the estimation was done at the end of the 21st century.

I said E for proper comparison.

E properly compares the right cost w/ the other cost. Everything elese is a bit ambigious. I preferred "the cost to the average individual" to "the average individuals cost"

Estimated at is not idiomatic hence options A,B,C,D out .
Also the modifier average is not clear who is it modifying individual or cost --> A, B , C .
Hence E clearly stands out .
