Why the other options are wrong
- A. A wheal is an itchy, swollen lesion caused by insect bites or allergies, often temporary and not typically pus-filled.
- C. A macule is a flat, discolored spot on the skin, not elevated or pus-filled.
- D. A bulla is a large blister containing watery fluid, larger than a pustule.
