There is no effective treatment for which condition?

• A. There are numerous cures that reverse vision loss.
• B. Early therapy reverses vision loss.
• C. There is no effective treatment.
• D. Treatment fully prevents further vision loss.

Answer: (C)

The main idea here is matching the claim about treatment availability to the prompt. The question asks for a condition with no effective treatment, so the best choice is the one that literally states there is no effective treatment. That option stays consistent with the prompt.

The other statements assert that there are cures, early therapies that reverse vision loss, or treatments that fully prevent further vision loss. If those were true, there would be an effective treatment, which would contradict the idea of “no effective treatment,” making them inappropriate.

So, the answer that says there is no effective treatment is the only option that aligns with the question’s premise, making it the correct choice.
