Plz explain why D is not a better choice since the sentence starteed with past tense and D appropriately continues the sentence in past tense.

I can think of only one difference

B is investigating the effects whereas D seems to investigate the changes.
Looks like a case of misplaced modifier.
Opinions anyone?

D indicates that the conditions themselves haven't changed but only their effects have. that's not the intended meaning of the original sentence


B is the right answer

Tough one. I think B is correct answer.

A. is out for using "experiments that would investigate...". Here investigation is happening at the same time, so "investigating" should be a better option. If we choose "would" (which is past of "will"), it sounds as if the investigations will happen at a later stage.

B. Correct. B is using "would" in the phrase "changes in working condition would have". Clearly the changes (i.e. the result of experiment) will come at a later stage, and not at the same time.
Present participle form of "investigating" is correctly used, modifying the experiments.

C.Sounds awkward and wordy. "what" is redundant. Better option would have been "investigating the effects" rather then "investigating what the effects"

D. "that investigated" sounds as if the experiments just invetigated once. "working conditions effects' on" sounds awkward. Also it sounds as if changes have happened on "working conditions effects' " and not on "working conditionS"

E. "what" is redundant. Infinitive form "to investigate" would have been better if we wanted to express the intention for conducting experiments. But here experiments are already in progress.

"effects" of "changes, not of "working conditions"

I never like picking up a choice which has an inanimate object in possessive.
Further, here the possessive on "working conditions" doesn't make any sense.

The effects were due to CHANGES in something, not due to that something.

please post questions without OA's highlighted.

The question is talking about "effects of changes in working conditions" as in B, and not "changes in...effects" as in D.
