Developed gradually at Los Alamos National Laboratory over the last 30 years, a groundwater model called Finite Element Heat and Mass (FEHM), which can accurately simulate the migration of water pollutants through any body of water regardless of its size, is now used by scientists for a variety of ecological purposes.

Yes a long one indeed and a frightening one too apparently, if not gone by the book.
The clue here is that the phrase “called Finite Element Heat and Mass (FEHM)” modifies the groundwater model and hence has to touch that particular noun phrase. As such, you can not separate both of them. Otherwise, the model called FEHM will rather modify undue things and distort the meaning as in C, D and E.
Between A and B, B has no conjunction to conjugate the two adjectivals that modify the ground water model.
A amends the conjugation problem, by converting the second adjective into a subordinate clause and by using " which", a relative pronoun that truly modifies the groundwater model.
While this sentence is long and contains many modifiers, it is actually correct as written. The first phrase (developed gradually at...) is a participial phrase that is followed immediately by the subject—a groundwater model—that it modifies. In the third phrase, the nonrestrictive clause beginning with which can... immediately follows FEHM (the thing which can), and is properly set off by commas so that the verb beginning the final phrase, (is now used...), is also properly linked to FEHM, it's subject.
Hi martie, are you using the on-line course of Knewton? How real are its questions compared with the GMAT Prep and the OG? I'm thinking in buying their course.
Thanks!
