Correct Answer: D

Rationale: Caput succedaneum is a condition characterized by the swelling of tissue over the presenting part of the infant's head during delivery. It is commonly a result of prolonged labor or vacuum extraction. Unlike cephalohematoma, caput succedaneum does cross the cranial suture lines. This condition typically resolves within a few days to a week after birth without intervention. It is important to monitor the infant for any complications or signs of infection during the resolution process.
