Urticaria is characterized by which of the following?

Explanation:
Urticaria presents as itchy, erythematous, raised wheals (hives) caused by transient edema in the superficial dermis from mast cell histamine release. The hallmark is pruritus with well-demarcated, red, raised lesions that can appear and fade over a short period. This is why the description “hives, pruritic red raised wheals” fits best. The other options describe non-itchy plaques, macules without edema, or blistering on the palms, none of which capture the typical itchy, edematous wheals of urticaria.
