Which of the following symptoms is commonly associated with allergic rhinitis?

The presence of a runny or stuffy nose is a hallmark symptom of allergic rhinitis. Allergic rhinitis occurs when the immune system overreacts to allergens such as pollen, dust mites, or pet dander, leading to inflammation in the nasal passages. This inflammation results in excessive mucus production, which manifests as a runny nose. Additionally, the swelling of the nasal membranes can cause nasal congestion, leading to a "stuffy" sensation.

Other symptoms associated with allergic rhinitis may include sneezing, itchy nose, and itchy or watery eyes. While fatigue can occur due to disrupted sleep or the body's response to allergies, and while skin rashes can appear in some allergic responses, they are not the primary symptoms of allergic rhinitis. Fever is typically associated with infections rather than allergic conditions, thus further clarifying why the runny or stuffy nose is the most relevant symptom in this case.
