A．not only as alaxative, but also a skin-softening lotion and it was a construction

B．as not only alaxative, but also a skin-softening lotion, and it was a construction

C．not only as a laxative but also as a skin-softening lotion and as aconstruction

D．as not only alaxative but as a skin-softening lotion and in construction, as a

E．not only as alaxative, but a skin-softening lotion and in construction, a

答案是C，但是我选的是B。B语法也没有错鸭，C的话很奇怪，为啥子not only, but also后还跟了and 并列。
希望各位大神帮我解答一下。(๑•̀ㅂ•́)و✧谢谢啦。

我看到大神们说it指代没任何问题

我自个觉得it指代不明，而且即便指代没问题，也没必要 s +v ,,,,and v ...根本不需要第二个句子...直接v and v修饰同一主语
一大神认为b只是结构不对称，简洁

自己看看大神如何说

In this question, (B) is 100% grammatically correct, but it is not a good answer. Let's think about this. We are talking about uses of something. The most efficient way would be to say:
Castor oil was used as X, Y, and Z.
For whatever reason, the author wanted to highlight the contrast between the use as a "laxative" (something they put inside their bodies) with the other external uses. The author creates this contrast with the "not only . . . but also" structure. Thus,
Castor oil was used not only as a laxative, but also as Y and as Z.
That's still very elegant, and this is exactly what (C) does.
By contrast, (B) introduces a new clause for the third factoid, rather than simply include it on the same list. That's enormously clunky! New clauses should introduce something genuinely new, something that opens new logical ground. Why start an entire new independent clause for a single item that simply could be added to a list? That's an astonishingly poor rhetorical choice! There's no sense of elegance and style. This version is an absolute embarrassment compared to (C).

What's particularly tricky about this question is that the prompt also makes the same rhetorically disastrous choice, so this might make (B) appear not too bad. I am sure many GMAT takers focused exclusively on grammar fell for the trap of (B). Meanwhile, the hyper-literalist would see the change in (C) and think that's a "change in meaning," rather than simply the first appearance of high quality writing among the answer choices. These official questions are brilliant, and they are crafted at a very sophisticated level. The student who focuses purely on grammar will not fare well on these questions.

哇，说的好有道理，好棒；大致已经明白了，谢谢大神。就是我还想问一下，在not only X, but also Y and Z中，我可不可以把Y and Z看成并列到but also 底下。因为我不是很理解三个并列，为啥要在not only... but also...后面再加一个and。

看看这段话

正常时as a, as b ,and as c
但作者希望高亮a和b的对比，所以用了 only not as a but also as b
