Correct Choice here is B
First let us talk about E

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

The red portion does not makes sense.

Option A: The invesitgation has already happened. we need simple past, not "would investigate"
Option C: This here is just too wordy to be given a serious consideration.
Option D: This changes the meaning and makes "working conditions" the main noun. Whereas the main noun should be "effects"

Correct option: B
