Here is my take.
a) Modifier issue. Ing modifier when following a clause imply that the action is happening at the same time. How can you have appearing and vanishing together. Also, the other usage of ing modifiers is to indicate a consequence- again something which is nonsensical in this case.
b) This can't be right. If 99% of the species that appeared have disappeared, then it means that some species still appear because not all of them have disappeared(not the best way to represent what I mean, but hope this will do :D). How can you then use Past tense "appeared". It should be have appeared as the species still continue to show up.
c) A blunder .
d) redundancy- of 500 million and of them again later in the sentence
e) No obvious errors

16. Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.

The essence o the nature of evolution is that it is an ongoing and eternal affair.

A. Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing --- modification is unclear. With comma + vanishing modifying the action of five hundred million species, appearing.-It looks incongruous.

B. Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth have vanished. -- that appeared is incongruous
C. Vanished are nearly 99 percent of the five hundred million different species of living creatures that appeared on Earth. -- that appeared is incongruous as explained at the top

D. Of five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent of them have vanished. Correct

E. Of the five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent have vanished. -- One cannot put a cap the number of species in evolution. There are so many that are evolving silently without our knowledge; hence, the use of 'the ', a factor that denotes an entirety is inappropriate

B. Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth have vanished.

C. Vanished are nearly 99 percent of the five hundred million different species of living creatures that appeared on Earth.

D. Of five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent of them have vanished.

E. Of the five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent have vanished.

in A and D "them" has no clear noun to which it can refer . there is some ambiguity
acc. to E is fragment as "Of the five hundred million different species" does not have a verb
C alters the meaning completely
