**Core Concept**
A subdural hematoma is a type of **traumatic brain injury** characterized by the accumulation of blood between the **dura mater** and the **arachnoid mater**. This condition often results from **head trauma**. The underlying principle involves the rupture of **bridging veins**.

**Why the Correct Answer is Right**
The correct answer is related to the mechanism of injury, which typically involves a **severe head injury** causing **acceleration-deceleration forces** that lead to the rupture of **bridging veins**. These forces can occur during events like falls, vehicle accidents, or assaults. The rupture of these veins leads to bleeding into the **subdural space**.

**Why Each Wrong Option is Incorrect**
**Option A:** Is incorrect because, although it could be a possible cause, it's not the most common one.
**Option B:** Is incorrect as it's not directly related to the most common cause of subdural hematoma.
**Option C:** Is incorrect because it refers to a different type of injury.
**Option D:** Is incorrect as it's not the most common cause.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that subdural hematomas can present with **altered mental status**, **focal neurological deficits**, and sometimes **seizures**. Prompt recognition and management are critical.

**Correct Answer:** D. Rupture of bridging veins.
