I picked answer E instead of C when I was in a class and never got an understanding of how I would know in the future that C is the correct answer.
I didn't pick C because from the premise, I only got that the hemoglobin would be more effective than itself after picking up additional molecules, but I couldn't say for certain that it would be more effective than a different hemoglobin, even if it had already picked up three molecules. I see that E was using very strong S&N language, so I guess I can see why it was wrong. Still, even though this is a MBT, neither answer seems necessarily true.
