Final answer:
A cesarean section was used to reduce the risk of maternal infection to the baby during childbirth due to Cynthia's active genital herpes.
Step-by-step explanation:
The form of delivery used for Cynthia, who has active genital herpes, was a cesarean section. This form of delivery was chosen to reduce the risk of maternal infection to the baby during childbirth. Genital herpes can be transmitted to the baby when passing through the birth canal, even if there are no visible lesions.
