@nybard (E) doesn't work because while the sufficient condition is properly invoked by the stimulus, i.e. only one strategy carries the possibility of success, the necessary condition of (E) does not.
We are not changing the circumstances as much as possible to fit this strategy. This would require giving the patient disease Y.
Notice the difference in (D), i.e. "one's strategy must be based on the assumption that this circumstance is in fact favorable." We are going to assume that the patient has disease Y.
Hope this helps! Please let us know if you have any other questions.

I see why D is the correct answer, but can you also explain why A is incorrect?
Thanks!

could you please explain why C is incorrect?

@erojas In this case, we’re not just treating both diseases instead of finding out which it is. We cannot find out which it is, and only one has treatment, so we’re going ahead with the one option we have. This is distinguishable from A, which is about the importance of either finding out what they have or acting on it; we don’t have an option to find out what they have, so the importance of it is irrelevant.
@DanielDePasquale Here, we’re acting on the assumption the patient has disease Y, but we’re not testing it, which is what C suggests we’re doing. We’re just going ahead and acting as if we know they do in fact have Y.
