**Core Concept**
The degree of a burn is determined by the depth of tissue damage, which is often classified into four categories: first-degree (superficial), second-degree (partial-thickness), third-degree (full-thickness), and fourth-degree (eschar formation with nerve damage).

**Why the Correct Answer is Right**
The burn shown in the image is a second-degree burn, also known as a partial-thickness burn. This type of burn involves damage to both the epidermis and the dermis, but the dermal layer remains intact, allowing for some sensation and bleeding from the wound. The presence of blisters and a pinkish-red coloration are characteristic features of second-degree burns. The dermal layer's intactness allows for the wound to heal with minimal scarring.

**Why Each Wrong Option is Incorrect**
**Option A:** First-degree burns only involve the epidermis and do not present with blisters or significant damage to the dermal layer.
**Option B:** Third-degree burns extend through the entire dermal layer and often result in eschar formation, with minimal sensation and no bleeding from the wound.
**Option C:** Fourth-degree burns extend through the dermis and into deeper tissues, such as muscle and bone, and present with significant nerve damage and eschar formation.

**Clinical Pearl / High-Yield Fact**
Second-degree burns often require pain management and wound care, but they can be managed on an outpatient basis. The key to preventing infection and promoting healing is keeping the wound clean and moist, and covering it with a non-adherent dressing.

**Correct Answer: B. Second-degree burn.**
