Final answer:
Amniotic fluid can disrupt the integrity of the newborn's skin, causing rash and vulnerability to bacterial infections.
Step-by-step explanation:
The correct answer is C) Amniotic fluid. Amniotic fluid is essential for protecting the fetus during pregnancy, but it can disrupt the integrity of the newborn's skin. The amniotic fluid contains substances like meconium, which can irritate the delicate fetal skin and cause a rash. Additionally, meconium interferes with the antibiotic properties of the amniotic fluid, making the newborn more vulnerable to bacterial infections.
