Which of the following would be indicated by the prefix "Urtic-"?

The prefix "urtic-" is derived from the Latin word "urtica," meaning "nettle." In medical terminology, this prefix is associated with conditions that involve skin reactions characterized by raised, itchy welts known as hives or urticaria. When you encounter the prefix "urtic-," it typically indicates a connection to these types of rashes, which are often allergic in nature and result in the temporary elevation of the skin. This makes the association with rash or hives the most accurate choice.

In context, other choices such as fungal infection, viral infection, and dermatitis refer to different causes and types of skin conditions that do not specifically relate to the characteristics implied by the prefix "urtic-." For example, fungal infections are caused by fungi and dermatitis generally refers to inflammation of the skin without the specific indication of the raised, itchy welts associated with urticaria.
