## **Core Concept**
Wolf's graft refers to a type of skin graft used in dermatological and plastic surgical procedures. It involves transplanting a full-thickness skin sample from one part of the body to another. This technique is often utilized for cosmetic or reconstructive purposes.

## **Why the Correct Answer is Right**
The correct answer, **C. Full-thickness skin graft**, is right because Wolf's graft specifically involves the transfer of a complete layer of skin, including the epidermis and the entire dermis. This type of graft is chosen for its aesthetic benefits, as it provides a more natural appearance and less contraction compared to split-thickness skin grafts.

## **Why Each Wrong Option is Incorrect**
- **Option A: Split-thickness skin graft** is incorrect because Wolf's graft involves a full thickness of the skin, not just a portion of it.
- **Option B: Dermal graft** is incorrect as it does not specify the inclusion of the epidermis, which is a critical component of Wolf's graft.
- **Option D: Composite graft** is incorrect because, although it involves multiple layers, Wolf's graft specifically refers to a full-thickness skin graft, not a graft composed of different types of tissues.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that Wolf's graft, or full-thickness skin graft, has limited donor sites due to the full thickness of skin being taken, which can lead to scarring. Common donor sites include behind the ear, eyelids, and the supraclavicular area.

## **Correct Answer:** C. Full-thickness skin graft
