**Core Concept**
Re-epithelialization is the process by which the epithelial layer of the skin is restored after injury, such as burns. This process involves the migration and proliferation of epithelial cells to cover the denuded area.

**Why the Correct Answer is Right**
In second-degree burns, the epidermis is partially destroyed, but the dermal layer remains intact. The dermal-epidermal junction provides a scaffold for re-epithelialization to occur. The process begins with the migration of epithelial cells from the surrounding skin, which are guided by growth factors and chemokines. These cells then proliferate and differentiate to form a new epithelial layer. Re-epithelialization typically occurs within 7-14 days in second-degree burns.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because re-epithelialization does not occur in third-degree burns, where the dermal layer is also destroyed.
**Option B:** This option is incorrect because re-epithelialization occurs around the edges of the burn, not within the center of the wound.
**Option C:** This option is incorrect because re-epithelialization is a process that occurs in the epidermis, not in the dermis.

**Clinical Pearl / High-Yield Fact**
Re-epithelialization is an important factor in wound healing, and it can be influenced by various factors, including the size and depth of the wound, the presence of infection, and the patient's overall health.

**Correct Answer: B. around the edges of the burn.**
