The correct answer is first degree burn.
Explanation:
Burns are classified into first degree, second degree, and third-degree burns. The first-degree burn is considered the mildest burn out of all three types. The example of first-degree burn is common sunburn.
In the first degree burn, the skin epidermis is affected but the dermis layer is not harmed. The area of burn appears red and is quite painful. No formation of blister occurs in the first-degree burn and it heals in 3-5 days.
