Chimpanzees are humans’ closest relatives, share 98% of the genetic DN

I'm sorry, but this is in no way a valid question.

First, while D is superficially parallel, that particular list of elements is not truly parallel in its content. Only the first item in the list ("sharing . . . DNA") can reasonably modify the initial clause. It explains how chimps are our nearest relatives. The other items in the list are just random things that we have in common with many creatures, from orangutans to birds! That consideration alone completely eliminates D-E, and since the other choices fail for their own reasons, that leaves us with no good answer. Even if A-C were revised, we wouldn't want to present all these items as a random, disconnected list, either. The whole thing just needs to be redone.

Further, while there is certainly no rule against the use of "being" in SC, there's a reason so many of us learn to avoid the word in most constructions, and D gives us a good example. We shouldn't use "being" to try to turn an adjective ("handy") into an activity ("being handy"). It may seem to fit grammatically, but it doesn't make that part a reasonable match for the other items in the list.

Additionally, "the genetic DNA" is redundant and unidiomatic. The sentence should just say "DNA." (Even if we wanted to distinguish between germline and somatic DNA, both types are still genetic.)

I wouldn't spend too much time on this one, but we can tell by the OA that the intent was for the last part with "they" to be one of the items in the list. Adding "they" was just a way to ruin the parallelism. There's no reason to separate out that item in particular, so while could fix this grammatically by ending the previous list with AND before moving on to the tool part, that still wouldn't make for a good sentence.
