The preferred manner of delivering the baby in a gravido-cardiac is vaginal delivery assisted by forceps under epidural anesthesia. The main rationale for this is:
A To allow a gradual shifting of the blood into the maternal circulation
B To prevent perineal laceration with the expulsion of the fetal head
C To allow atraumatic delivery of the baby
D To make the delivery effort free and the mother does not need to push with contractions
