**Core Concept**
Congenital Rubella Syndrome (CRS) refers to a group of congenital anomalies that occur in infants infected with the Rubella virus in utero. The classic triad of CRS includes a combination of clinical features that are characteristic of this condition.

**Why the Correct Answer is Right**
The classic triad of CRS includes **cataracts**, **heart defects**, and **hearing loss**. This triad is due to the teratogenic effects of the Rubella virus on the developing fetus. The virus can cause damage to the developing eyes, heart, and auditory system, leading to the characteristic features of CRS.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not part of the classic triad of CRS. However, other features of CRS include intellectual disability, microcephaly, and thrombocytopenia.
* **Option B:** This option is not a feature of CRS. While some cases of CRS may present with jaundice or hepatosplenomegaly, these are not part of the classic triad.
* **Option C:** This option is not a feature of CRS. While some cases of CRS may present with hepatosplenomegaly or lymphadenopathy, these are not part of the classic triad.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the classic triad of CRS can be prevented by vaccinating women of childbearing age against Rubella. This can significantly reduce the incidence of CRS and its associated complications.

**Correct Answer:** D
