Final answer:
The type of burn similar to a sunburn is a Superficial partial-thickness burn, also known as a first-degree burn, which affects only the epidermis and generally heals on its own.
Step-by-step explanation:
The type of burn that is similar to a sunburn is A. Superficial partial-thickness burn. Sunburns cause damage to the outer layer of skin, the epidermis, by UV light from the sun or tanning lamps. This results in what's known as a first-degree burn. A superficial partial-thickness burn, like a mild sunburn, usually heals on its own within a few days.
First-degree burns affect only the epidermis. When the skin experiences a superficial burn, it may become painful and swollen, but these burns typically do not cause permanent damage and generally do not require professional medical treatment unless they cover a large area or are on the face or a major joint.
For more severe burns, such as second-degree burns, both the epidermis and a portion of the dermis are affected. These burns can result in swelling and painful blistering. Third-degree and fourth-degree burns are even more severe, involving complete destruction of the epidermis and dermis, and can extend to the muscle and bone beneath, necessitating immediate medical care.
