**Core Concept:** Congenital Morgagni cataract is a type of congenital cataract that is characterized by the presence of a small, round, and white opacity in the lens of the eye. It is a developmental abnormality that occurs due to the failure of the lens fibers to separate during fetal development.

**Why the Correct Answer is Right:** Congenital Morgagni cataract is associated with the failure of the lens fibers to separate properly during fetal development. This results in the formation of a small, round, and white opacity in the lens, leading to vision impairment in the affected individual.

**Why Each Wrong Option is Incorrect:**

A. **Wrong Option A:** None

B. **Wrong Option B:** None

C. **Wrong Option C:** None

D. **Wrong Option D:** None

**Clinical Pearl:** Congenital cataracts, including Morgagni cataract, should be promptly diagnosed and treated to prevent vision impairment or blindness in affected infants. Early surgical intervention can significantly improve the visual outcome.

**Correct Answer:** Congenital Morgagni cataract is associated with the failure of the lens fibers to separate properly during fetal development. This leads to the formation of a small, round, and white opacity in the lens, resulting in vision impairment in the affected individual.
