**Core Concept**
Shaken baby syndrome, also known as abusive head trauma, is a form of child abuse that occurs when a person violently shakes an infant or child, leading to severe brain injury and potentially life-threatening consequences. This condition is caused by the sudden and forceful movement of the head, which results in the brain being jostled back and forth within the skull.

**Why the Correct Answer is Right**
The triad of shaken baby syndrome consists of three key components: subdural hematoma, retinal hemorrhage, and encephalopathy. Subdural hematoma is a collection of blood in the space between the brain and the skull, often resulting from the tearing of blood vessels. Retinal hemorrhage refers to the presence of bleeding in the retina of the eye, which can be caused by the increased intracranial pressure associated with shaken baby syndrome. Encephalopathy is a term used to describe brain injury, which can manifest as altered mental status, seizures, or even coma. The combination of these three findings is highly suggestive of shaken baby syndrome.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe the classic triad of shaken baby syndrome. While subdural hematoma is a component, retinal hemorrhage and encephalopathy are not explicitly mentioned.

**Option B:** This option is incorrect because it does not include all three components of the triad. Subdural hematoma and retinal hemorrhage are mentioned, but encephalopathy is not.

**Option C:** This option is incorrect because it is too broad and does not specifically mention the triad associated with shaken baby syndrome. Subdural hematoma and retinal hemorrhage can occur due to various causes, not just shaken baby syndrome.

**Option D:** This option is incorrect because it is not a recognized component of the triad of shaken baby syndrome. While cerebral edema can occur in the context of shaken baby syndrome, it is not one of the classic findings.

**Clinical Pearl / High-Yield Fact**
The "shaken baby" triad is often remembered using the acronym "S.R.E.": Subdural hematoma, Retinal hemorrhage, and Encephalopathy. This mnemonic can help medical professionals quickly recall the classic findings associated with this condition.

**Correct Answer:** A. Subdural hematoma, retinal hemorrhage, and encephalopathy.
