Final answer:
The treatment options listed are more suited to live tissue, and while not directly relevant to embalming, cold compress, topical ointments, and aloe vera gel can help soothe first-degree burns in living tissue.
Step-by-step explanation:
The question concerns the treatment of first-degree burns during the embalming process. Among the four options provided, the correct treatment for first-degree burns is not directly mentioned, because embalming is a practice that deals with the preservation of bodies after death, not living tissue. However, in the context of general first aid (not embalming), first-degree burns can be handled with cold compress application to soothe the skin, topical ointments to assist in healing and prevent infection, and aloe vera gel application to provide cooling relief. These methods can reduce pain and swelling, and support the natural healing process.
