(A) fatigue among shift workers, and have raised not parallel
(B) fatigue among shift workers, and raisedthis leades to have reduced raised- nonsensical
(C) and fatigue among shift workers while raisingcorrect
(D) lowered fatigue among shift workers, and raisedsame as b
(E) and fatigue among shift workers was lowered while raising
was lowered spoils the sentence

we have to parallel have reduced [sickness] [sleeping], and [fatigue] - parallel nouns while raising the efficiency. There C must be the correct answer

Concept tested: Parallelism, “items in a list”
Difficulty level: Hard
Illustration: When we provide a list of items using commas we must maintain the
following structure.
A, B, C and D.
This is a proper parallel structure concerning items in a list, and this structure
needs to be maintained in a clause. Another thing of importance in this sentence
is the contrast that is presented.
This sentence says that “shift work equations” has reduced some stuffs but raised some other stuff. So using “and” to connect this two
relationship affects the meaning of the sentence.
In A, parallel structure is brokenusing the sudden “have”, “and item in the list” construction is not maintained.
According to “item in the list” the construction could be “A has reduced X, Y and Z,but has raised P, Q and R.
So we definitely need “and” before “fatigue among shift
workers”
This concept eliminates A and B.
D uses redundant construction “reduced” + “lowered”, which could also act as a fatal double negative.
E breaks voice parallelism.
We can’t suddenly introduce a passive voice in a list construction where other items are in active voice.
C is the correct answer which maintains “item in thelist” and introduces the contrast using “while”.

Broken piece by piece by @adineo !!! Kudos

nothing more to add!!! except How GMAT tricks us by putting a modifier - "based on studies of the human sleep cycle" in between Subject and Verb and confusing us.

How to ***** is A no parallel ? Seriously, answers like this are killing me.

Perfectly parallel

Ok, let me try and break this down for you.

THE TRICK HERE : whenever you see a comma(,) before 'and' then it is a list in the form of x,y, and z and you have to make parallel all three x and y and z.

Thus we have to parallel have reduced [sickness] [sleeping], and [fatigue] - parallel nouns while raising the efficiency.

Therefore C must be the correct answer.

I really hope this helps you

I chose B.. i thought raised should b parelel..

but after luking at all explanation i must say, C is the rite answer..

got lesson from this question dont be crazy to mark the answer, if u see the parrelel structure..one should know what does sentence want to convey !!

reduced and raise production can not be parelel, for raise it must another dependent word ,such as while to further procede the sentence.

Good question.
I chose C after deliberating for a good 1:25 mins. On the one hand I wasn't too happy with the participle "raising" used instead of the simple past "raised" in C but on the other hand I was sure that the items in list rule absolutely must be complied with and should take priority over everything else.
