Correc toption is D
Step-by-step explanation:
A boil, also known as a furuncle, is a red lump in the skin that is often warm and painful to the touch. It represents a localized accumulation of pus and tissue debris due to a skin infection, commonly by Staphylococcus bacteria. When multiple boils join together and form into a deeper lesion, this is called a carbuncle, which may be associated with systemic symptoms such as fever and a general feeling of illness and typically requires medical treatment.
Upon encountering boils or furuncles, especially when they are persistent or worsening, individuals should seek medical attention. This is particularly important if the boils spread, increase in number or size, or if systemic symptoms like fever and chills appear. It's essential to manage these infections promptly to prevent complications such as necrotizing fasciitis, which is a rapidly progressing and severe type of infection.
