**Core Concept**
The question refers to a type of injury pattern where the skin marks or tyre marks are found on the body, indicating a specific type of trauma. This is a classic example of a pattern of injury that can be used to determine the type of force or object that caused the injury.

**Why the Correct Answer is Right**
The correct answer is an example of a "bruise" or more specifically, a **contusion**, which is a type of non-penetrating injury caused by blunt force trauma. In this case, the tyre marks on the body suggest that the child was run over by a rickshaw, resulting in a contusion. Contusions occur when blood vessels are damaged, causing blood to leak into the surrounding tissue, resulting in discoloration and swelling. The tyre marks on the body indicate the path of the tyre and the force exerted on the child.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not relevant to the scenario described in the question.
**Option B:** This option is incorrect because it does not accurately describe the type of injury pattern depicted in the question.
**Option C:** This option is incorrect because it is not a specific type of injury pattern that matches the description in the question.

**Clinical Pearl / High-Yield Fact**
It is essential to note that the presence of tyre marks on the body can be a crucial piece of evidence in determining the cause of injury, particularly in cases of suspected child abuse or neglect. The pattern of tyre marks can help investigators reconstruct the events surrounding the injury.

**Correct Answer: C. Contusion.**
