**Core Concept**
Febrile seizures are a common condition in children, often occurring between 6 months to 5 years of age. They are typically associated with a sudden increase in body temperature. Understanding the risk factors for future seizures is crucial for managing these children.

**Why the Correct Answer is Right**
One of the key risk factors for recurrent febrile seizures is a family history of epilepsy. Children with a first-degree relative (parent or sibling) with a history of epilepsy have an increased risk of developing epilepsy. This is likely due to genetic predisposition and shared genetic mutations that contribute to epilepsy susceptibility.

**Why Each Wrong Option is Incorrect**
**Option A:** Complex febrile seizures, which are prolonged or recurrent seizures, are indeed associated with an increased risk of developing epilepsy. Therefore, this option is incorrect.
**Option B:** A history of complex febrile seizures is a risk factor for developing epilepsy, making this option incorrect as well.
**Option C:** Children with a family history of epilepsy have an increased risk of developing epilepsy, making this option incorrect.

**Clinical Pearl / High-Yield Fact**
A child with a family history of epilepsy is at increased risk of developing epilepsy, particularly if there is a first-degree relative with a history of epilepsy.

**Correct Answer: D. All of the above**
