**Core Concept**
Battledore placenta, also known as a velamentous insertion of the umbilical cord, is a rare type of placental anomaly where the umbilical cord inserts into the amniotic membrane rather than the placental mass. This condition is associated with an increased risk of complications during pregnancy.

**Why the Correct Answer is Right**
The velamentous insertion of the umbilical cord can lead to an increased risk of fetal growth restriction, preterm birth, and placental abruption due to the potential for cord compression and rupture. The absence of a secure placental attachment can compromise fetal blood flow, leading to growth restriction and other complications. This condition is often associated with other placental anomalies, such as placenta previa and placental infarction.

**Why Each Wrong Option is Incorrect**
**Option A:**: This option is incorrect because it does not specify a particular complication associated with battledore placenta. While placental abruption is a possible complication, it is not the only one.
**Option B:**: This option is incorrect because it is too vague and does not accurately reflect the specific risks associated with battledore placenta. Fetal growth restriction is a possible outcome, but it is not the most significant risk.
**Option C:**: This option is incorrect because it is not a direct complication of battledore placenta. Placenta previa is a separate condition that can occur in conjunction with battledore placenta, but it is not the most significant risk.

**Clinical Pearl / High-Yield Fact**
Battledore placenta is a rare but significant placental anomaly that requires careful monitoring during pregnancy. It is essential to recognize the signs and symptoms of this condition to provide timely intervention and prevent complications.

**Correct Answer:** D.
