Final answer:
The risks of birth complications with vaginal birth after cesarean (VBAC) include an increased risk of uterine rupture and other complications compared to a planned repeat Cesarean birth.
Step-by-step explanation:
The accurate answer to the question is option 1) Increased risk of uterine rupture and other complications compared to a planned repeat Cesarean birth. A vaginal birth after cesarean (VBAC) carries a higher risk of uterine rupture compared to a planned repeat cesarean birth. Uterine rupture is a serious complication where the incision made during the previous cesarean birth tears open, which can lead to hemorrhage and other complications.
