**Core Concept**
Congenital Rubella syndrome occurs when the Rubella virus infects a pregnant woman, particularly during the first trimester, and is transmitted to the fetus. This can lead to a range of serious birth defects. The underlying principle being tested is the understanding of the clinical manifestations of congenital Rubella syndrome.

**Why the Correct Answer is Right**
Since the correct answer options are not provided, let's discuss the common manifestations of congenital Rubella, which include deafness, cataracts, congenital heart disease, and intellectual disability. These occur due to the virus's impact on fetal development during critical periods of organogenesis.

**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option, we can't directly address it, but common manifestations like deafness are well-documented.
**Option B:** Similarly, without specifics, we know that cataracts are a common ocular finding.
**Option C:** Again, lacking the option, but heart defects are frequent in congenital Rubella syndrome.
**Option D:** Assuming this might be a less common or incorrect manifestation, without the text, we can't directly refute it.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that congenital Rubella syndrome can lead to severe and permanent disabilities, emphasizing the importance of Rubella vaccination in preventing such outcomes.

**Correct Answer:** D. Normal vision
