**Core Concept**
Injury caused by a pedestrian in a vehicular accident can be classified based on the mechanism of injury. The type of injury depends on the object on the road that the pedestrian strikes, which can be a vehicle, a pedestrian, or an object.

**Why the Correct Answer is Right**
When a pedestrian is struck by a vehicle in a vehicular accident, the injury is typically caused by the vehicle itself. However, if the pedestrian strikes an object on the road, such as a lamppost or a sign, the injury is classified as a **pedestrian struck by an object**. This type of injury is distinct from being struck by a vehicle, as the force and mechanism of injury are different.

**Why Each Wrong Option is Incorrect**
* **Option A:** This is not a valid classification of injury caused by a pedestrian in a vehicular accident.
* **Option B:** This option is incorrect because it is a type of injury caused by a vehicle, not an object on the road.
* **Option C:** This option is incorrect because it is a type of injury caused by a pedestrian being struck by another pedestrian, not an object on the road.
