Several skeletal remains in Eastern China,  currently known as those of large prehistoric animals, were usually assumed to be those of  remains of exotic giant dragons and were widely adored.

A. currently known as those of large prehistoric animals, were usually assumed to be those of  "to be those of" in the end of the underlined sentence does not make any sense. It implies, "bones of those of exotic dragons. It should be just bones of exotic dragons. Unnecessary "those of" makes this answer choice wrong. Also, the past-participle modifier "currently known as" is not precise. We will see a better version that is used in the correct answer choice, eliminating any ambiguity 
B. bones known at present as of large prehistoric animals, were usually assumed as those of again it repeats the "those of" error of the option A.  
C. now known to be large prehistoric animals, were usually assumed to be "known to be large animals?" Holy smokes. It is illogically claiming skeletal remains are known to be large animals. Paraphrasing it- Sketel remains are now known to be prehistoric animals. There should be a preposition "of" to make the reference clear. 
D. bones now known to be those of large prehistoric animals, were usually assumed to be   This is the correct answer choice for it neither has the structure of participle modifier (maybe) incorrectly modifying the preceding noun (Eastern China) by using an absolute phrase to correctly modify the "skeletal remains" in the preceding clause, nor does this answer choice, incorrectly distort the meaning that option C does. Usage of "known to be those (bones) of prehistoric animals" is more precise and correct.  
E. presently known as from large prehistoric animals, were usually assumed as  "from prehistoric animals?" "of" is a much better preposition to convery the intended meaning.
