Answer 1

The incorrect option would be a. Target ""bulls-eye"" lesion with a necrotic center surrounded by pale macular middle area then by an erythematous peripheral ring.


While erythema multiforme can cause target-like lesions with a central necrotic area, it can have various other morphological traits, such as flat macules, papules, or even blisters.
