22. B is the correct answer. Urticaria produces lesions like seen in the photo. You commonly see them in the trunk and axilla, but you can see them anywhere. A diagnosis of angioedema cannot be made because it affects the lips and mouth but urticaria can be associated with it. Erythema multiforme lesions are target shaped. Vasculitis is seen more on the dependent areas of the body like the extremities and is is usually a deeper color. It can be seen anywhere though.
