What's wrong with options B and D

Our big issue here is that we have a list of three ideas that we want to be parallel. In E, this is done correctly:

Among the largest of the flying squirrels is the Japanese giant flying squirrel, which:

• measures two feet from the top of its head to the tip of its tail

• has a wingspan of more than a foot and a half

• weighs up to five pounds

In B, we have

Among the largest of the flying squirrels is the Japanese giant flying squirrel:

• measuring two feet from the top of its head to the tip of its tail

• a wingspan of more than a foot and a half

• weighing up to five pounds

This is not grammatical. The sentence would be grammatical if "a wingspan of more than a foot and a half" described "two feet from the top of its head to the tip of its tail", as in

Among the largest of the flying squirrels is the Japanese giant flying squirrel, :

• measuring two feet from the top of its head to the tip of its tail (a wingspan of more than a foot and a half)

• weighing up to five pounds

But wingspan is a measurement of wingtip to wingtip (or fingertip to fingertip) - not head to tail. So this meaning doesn't work.

In D, we have a similar issue - a list that isn't parallel

Among the largest of the flying squirrels is the Japanese giant flying squirrel, which:

• measures two feet from the top of its head to the tip of its tail

• with a wingspan of more than a foot and a half

• weighing up to five pounds

This is a question based on parallelism.
A. "it weighs" is not parallel to "measuring". So, A is out.
B. "a wingspan" doesn't give a clear picture that flying squirrel has a wingspan.
C. "which measure", "its wingspan" and "weighing" are not parallel.
D. "which measure", "with a wingspan" and "weighing" are not parallel.
E. It has a complete parallel structure. Hence, E is the answer.

What's wrong with options B and D

comma+doing refer to the subject of the main clause and works ad an adverb of the main clausse. in choice a and b, no subject from the main clause can refer to measuring. wrong.
in C, "its winspan is more than" is parallel with which clause? if it is parallel with "the largest is" , it is not logic and there is no connection between the two clauses. wrong
in D
with+noun+noun modifier can word as an adverb of the main clause, but this phrase dose not refer to the subject of the main clause as comma+doing does, so, "with wingspan" dose not refer to "which" and the sentence meaning is unclear. "wingspan " of what?
comma+doing, such as weighing must modify the main clause. it can not stand after "with+noun+noun modifier" grammatically. there is simplly no this pattern.
