Can You Please elaborately explain why option A is wrong. and what is the intended Meaning of the sentence?
Is it that They are changing the working conditions and its effect is being observed in the workers performance?

I also agree that this question is not a good quality question. Given the time context it is tough to use a present participle that denotes that the experiments are still investigating the performance.

I think the answer should be D. The wording is quite a mouthful, but not grammatically incorrect. On the other hand, B has the phrase "would have", which has two implications: (1) the effects are hypothetical (2) they happen at some future date. Both these implications alter the sense of teh sentence as given. I'd go with D

Would can also be used when reporting a past event.

I don't really like this question, as I find that choice D better expresses the meaning to be conveyed than does the OA. Still, I'll give you my reasoning.

In the mid-1920’s the Clyde Fan Factory of the Bosch Manufacturing Company was the scene of an intensive series of experiments that would investigate changes in working conditions as to their effects on workers’ performance.

A. that would investigate changes in working conditions as to their effects on workers’ performance

This choice does not express clearly what is being investigated. It starts off OK, when it says "investigate changes in working conditions", but "investigate changes in working conditions as to their effects on workers’ performance" is basically meaningless. Are the effects being investigated? This choice does not say so. It basically mushes a bunch of words together to sound as if it says something.

Also, it is not the case that the experiments "would investigate" the changes. The experiments did investigate the changes.

B. investigating the effects that changes in working conditions would have on workers’ performance

This choice basically makes sense. It clearly expresses that the purpose of the experiments is to investigate the effects of changes in working conditions.

I don't really like this choice as much as I like D, though, as to me it makes more sense that what was being investigated was not the effect that changes "would have" on worker performance but rather the effects that changes in working conditions actually have on worker performance.

C. for investigating what are the effects in workers’ performance that changes in working conditions would cause

This version is poorly worded. What was being investigated was the effects. Saying that they were investigating "what are the effects" throws in the wording of a question, "what are", where such wording does not make sense.

Also, "effects in" is not idiomatic. The expression commonly used is "effects on", which also makes more sense than "effects in".

D. that investigated changes in working conditions’ effects on workers’ performance

To me this is the best, most concise answer. It clearly conveys that the experiments investigated the effects of the changes. I guess we could argue that it would make more sense to put "effects" directly after "investigated" as choice B does.

In any case, the difference between this choice and choice B seems to me to be a style call rather than a clear case of one choice's being better than the other.

Perhaps "investigating" in B is more continuous than "that investigated" in this choice. Tough call. Anyway, overall, after considering this question for years, I still prefer this choice.

Meanwhile, do experiments themselves "investigate". Even that idea is debatable. So, on the whole, this question is not great.

E. to investigate what the effects changes in working conditions would have on workers’ performance

In this version "to investigate" does not make as much sense as "investigating" or "that investigated". The point is not that the experiments were merely "to investigate". The experiments actually did investigate. This point is a minor one, but it contributes to the elimination of this choice.

The big issue with this choice is the addition of the word "what". This word is totally unnecessary, and its presence results in the sentence's conveying a completely muddled meaning. This version conveys that the experiments investigated what the effects would have, as if the effects themselves would have something. You can see that this is the case by eliminating a few words to get the following:

"... experiments to investigate what the effects ... would have ..."

I choose D during the test and got incorrect, while analysing I picked B.
I'm really not sure what's going on here.
Is D incorrect because of that investigated changes ?

Incorrect OA (A).

If you could elaborate why you consider A is better than B, then it would be possible to discuss further. Please let us know exactly where you differ from the OE.

the reason i chose D over B was because D started with past tense and the sentence also has "was" making it more parallel, where as B is continuous. Where did i go wrong ?

This question is almost identical to a GMATPrep question, with just a couple of details changed -- and (B) and (D) in this thread are identical to their counterparts in the GMATPrep question.

So maybe this post or this post on the original GMATPrep question might help?

I think this is a poor-quality question. A, B and D says that, experiments would itself investigate, experiments investigating?? were the experiments themselves investigating? , Experiments themselves investigated?
I don't firmly agree with the solution

D. that investigated changes in working conditions’ effects on workers’ performance
E. to investigate what the effects changes in working conditions would have on workers’ performance

Bunuel I don't know who wrote the explanation, but explanations such as "wordy" or "awkward" is far from being useful. As you must know, the explanations from OG is criticized by many GMAT experts for the same reason. Also, I'm surprised to see this kind of explanation from a GMAT Club's CAT, since its QUANT CATs are regarded by many students to have a really high standard. If you be so kind, please take a look at the question to address this issues. Many tks!

I think D is equally well framed and uses the modifier correctly but ultimately changes the intended meaning, i.e. it should be "Effects" should have "changes" in condition and NOT "changes" in working conditions' "effect".

D has a serious meaning problem - it is in fact senseless:

Option D states that the investigation was about changes in effects on performance - this does not make sense. The intended meaning is about the change in working condition, not change in effects.

In D, it 'changes in working condition's effect' is given. I think 'changes in working condition' is working as a noun phrase here. Please clarify, why it should be considered 'changes in effects' but not 'changes in working condition's effect'
