• A. Chronic joint pain
• B. Rapidly spreading tissue death

Answer: (B)

Verified step by step guidance

1. Understand the definition of necrotizing fasciitis: it is a severe bacterial infection that causes the rapid destruction of soft tissue, including fascia and subcutaneous fat.
2. Identify the key clinical features of necrotizing fasciitis, which typically include intense pain, swelling, redness, and most importantly, rapidly spreading tissue death (necrosis).
3. Compare the given options with the known symptoms of necrotizing fasciitis: chronic joint pain is not typical, yellowing of the skin (jaundice) relates to liver issues, and persistent dry cough is a respiratory symptom.
4. Recognize that the hallmark or signature symptom of necrotizing fasciitis is the rapid progression of tissue necrosis, which distinguishes it from other conditions.
5. Conclude that the correct answer is 'Rapidly spreading tissue death' because it directly reflects the aggressive nature of necrotizing fasciitis.
