**Core Concept**
Congenital toxoplasmosis refers to the transmission of Toxoplasma gondii infection from a pregnant woman to her fetus, leading to various congenital anomalies and complications. This condition occurs when the parasite crosses the placental barrier, typically during the first trimester of pregnancy.

**Why the Correct Answer is Right**
The correct answer is related to the fact that congenital toxoplasmosis can cause severe neurological and ocular manifestations in the fetus. **Toxoplasma gondii** infection triggers an inflammatory response in the fetus, leading to damage in the brain and eyes. The parasite can also cause microcephaly, hydrocephalus, and chorioretinitis in the affected infant.

**Why Each Wrong Option is Incorrect**
**Option A:** This option might be incorrect because it is not a known consequence of congenital toxoplasmosis. However, without the actual option, it's difficult to confirm.
**Option B:** This option might be incorrect because it is not a characteristic feature of congenital toxoplasmosis. Congenital toxoplasmosis can cause a wide range of symptoms, but this option does not accurately describe a common manifestation.
**Option C:** This option might be incorrect because it is not a direct consequence of congenital toxoplasmosis. While the condition can cause various complications, this option does not accurately describe a typical outcome.

**Clinical Pearl / High-Yield Fact**
A key aspect of congenital toxoplasmosis is the importance of maternal screening during pregnancy. Pregnant women with a history of **Toxoplasma gondii** infection or exposure should be tested for IgG and IgM antibodies to detect potential transmission to the fetus.

**Correct Answer: A.**
