• B. Redness of the skin

Answer: (B)

Erythema specifically refers to redness of the skin, which results from increased blood flow to the capillaries near the surface of the skin. This increase in blood flow can be due to various factors, including inflammation, infection, allergies, or irritation. Erythema can be a visible indicator of an underlying condition, such as a rash or sunburn, and it is an important clinical sign that healthcare providers assess when evaluating a patient's skin and overall health. The redness is often localized, but it can also be widespread depending on the underlying cause. Understanding this term is essential for recognizing symptoms and making appropriate medical evaluations.
