**Core Concept**
Vaginal birth after caesarean section (VBAC) is a labor and delivery strategy for women who have had a previous caesarean section. The decision to attempt VBAC involves evaluating various risk factors and contraindications to ensure a safe outcome for both the mother and the baby.

**Why the Correct Answer is Right**
The correct answer is related to a condition that significantly increases the risk of uterine rupture during VBAC. Uterine rupture is a life-threatening complication that can lead to severe maternal and fetal morbidity. The condition in question is associated with a higher risk of uterine scar dehiscence due to the presence of a uterine anomaly that may compromise the integrity of the uterine wall.

**Why Each Wrong Option is Incorrect**
**Option A:**
*This option is incorrect because it is not a recognized contraindication for VBAC. Women with a history of previous uterine surgery may still be eligible for VBAC, depending on individual circumstances.*

**Option B:**
*This option is incorrect because it is not a contraindication for VBAC. Women with a previous low-transverse caesarean section scar are generally considered good candidates for VBAC.*

**Option C:**
*This option is incorrect because it is not a contraindication for VBAC. Women with a previous classical caesarean section may be at higher risk for uterine rupture, but this is not an absolute contraindication for VBAC.*

**Option D:**
*This option is correct because it is a recognized contraindication for VBAC. Women with a history of classical caesarean section, uterine surgery, or major uterine anomalies (such as a bicornuate or septate uterus) are at increased risk of uterine rupture and are generally not considered good candidates for VBAC.*

**Clinical Pearl / High-Yield Fact**
*Women with a previous classical caesarean section or major uterine anomalies should be counseled about the risks and benefits of VBAC and may be better suited for a scheduled repeat caesarean section.*

**Correct Answer:** D. A history of classical caesarean section or major uterine anomalies is a contraindication for VBAC due to an increased risk of uterine rupture.
