Which of the following is true about cesarean deliveries?

Cesarean deliveries can indeed be planned or unplanned, making this the accurate choice. A planned cesarean, sometimes referred to as an elective cesarean, occurs when there is a known indication for surgery prior to the onset of labor, such as a breech presentation or previous cesarean delivery. An unplanned cesarean may be necessary during labor due to complications that arise, such as fetal distress or failure to progress.

The other options do not accurately reflect the nature of cesarean deliveries. They are not always performed in emergencies; many are scheduled ahead of time for medical reasons. Additionally, cesareans can be performed on mothers regardless of whether it's their first child or not. Lastly, while cesarean deliveries can reduce some risks associated with vaginal births, they do not eliminate all risks connected with childbirth, such as surgical complications and recovery challenges for the mother.
