参考答案：D

解析：Neonates delivered by cesarean birth without any other contributing factors should have adequate stores of brown fat to control blood glucose levels. Stores of brown fat aren’t deposited until 36 weeks, so infants born at less than 36 weeks won’t have the necessary stores to maintain a normal blood glucose level. Neonates who have respiratory distress or are postdated will use up their stores of brown fat as a result of these complications.
