The answer is e.

Varicella-zoster immunoglobulin (VZIG) should be administered to the infant immediately after delivery if the mother had the onset of varicella within 5 days prior to delivery, and immediately upon diagnosis if her chickenpox started within 2 days after delivery. If untreated, about half of these infants will develop serious varicella as early as 1 day of age.

If a normal full-term newborn is exposed to chickenpox 2 or more days postnatally, VZIG and isolation are not necessary because these babies appear to be at no greater risk for complications than older children.
Acyclovir is not approved for use in early infancy
