Answer:
The correct answer is- second-degree burn
Step-by-step explanation:
Most of the sunburns are first degree but the overexposure of sun can even lead to second-degree burns. The first-degree burn is not very much complicated and include only the burning of the outer epidermis of the skin. It causes redness, pain, dryness at the site of burn but blisters are not formed.
Second-degree burn affects two layers of skin the epidermis and the dermis layer and the symptoms of second-degree burn are like first degree but additionally it has blisters and swelling at the burned area.
Therefore Susan had second-degree burn which is represented by the formation of the blisters. So the right answer is- second-degree burn.
