If you're unsure, then take the test in June. You can always try again with the new format in August (or later). But you'll never again have the chance with the current format. Best of luck!

Echoing many comments, I was confused between C and D for a long time including after initially getting the question wrong and several subsequent reviews.

Ultimately, I believe D is wrong because of the word "rectify." If the principle changed "rectify" to "avoid," then I think D could be the correct answer. D avoids any unfair outcome (everybody gets nothing). But does it rectify the situation? Rectify means "make right" or "correct." I'm convinced that D does not correct the corporation's error.

Meanwhile, C is not a perfect answer. But we don't have to find a perfect answer — only the most justified.

C says the Thimble Corporation is obligated to try to rectify any unfair result. Even if it tries, it does not necessarily fulfill an obligation to rectify any unfair result.

Because C is imperfect and D is almost correct, I'm surprised its difficulty on the curve is so low!
