It's just not a very well written question + answer choices. I would relieve yourself of the torment of "figuring it out".
As people have said, if we were simply trying to counter the claim that alternative medicine "has no effect at all", then (C) is a better answer than (D).
However, if we were being more holistic / more conversational / more common sense, we would interpret that final claim about "no effects at all" as "no positive medical effects at all".
After all, the paragraph is discussing the limitations of orthodox medicine to find ways to ease certain forms of suffering or cure certain diseases.
Alternative medicine is brought up in this context ... people to turn to it for "help" (not "hope"), because orthodox medicine has failed them.
So if you're playing along with the context / gist of the paragraph, then you interpret that final claim to be saying "alternative medicine doesn't have harmful side effects, because it's basically doing NOTHING [chemically / biologically] to your body."
Through this lens, (C) is not direct enough to be relevant. "Hope" is not itself a medical help, unless you consider it common knowledge that "hope" helps us to achieve some medical benefits.
(D), meanwhile, is opening a door through which we MIGHT be able to say that "alternative medicine can give patients something new to believe in, and that new belief can actually lead to an effective reduction in aches, pains, and allergies."
Correct answers on Weaken don't have to firmly establish the counterpoint we're wanting to make. If they open up the possibility for some doubt, they can still Weaken the case.
If you have an eyewitness who testifies that she saw Johnny at the crime scene,
and a lawyer says "Have you ever mistakenly thought you saw someone somewhere only later to discover you were wrong?", if the eyewitness says "Yes, sometimes I make mistakes about whether I saw someone somewhere", then we have weakened the prosecution's case at least somewhat.
Her saying that doesn't PROVE that she is wrong about identifying Johnny at the crime scene, but it opens up the possibility for some doubt.
