Which symptom is characteristic of allergic rhinitis?

Allergic rhinitis is primarily characterized by symptoms that arise from the body's immune response to allergens such as pollen, dust mites, mold, or pet dander. Watery eyes, or conjunctival tearing, is one of the hallmark symptoms of this condition. When exposed to allergens, the body releases histamines, which lead to inflammation and increased tear production, causing the eyes to water. This symptom often accompanies others associated with allergic reactions, such as sneezing, nasal congestion, and itching.

In contrast, dry cough, fever, and chest tightness typically suggest other respiratory conditions rather than allergic rhinitis. While a dry cough can occur with various respiratory disorders, it is not a defining feature of allergic rhinitis. Fever is indicative of an infection, such as a cold or flu, because allergic rhinitis does not cause a rise in body temperature. Similarly, chest tightness is more commonly associated with conditions like asthma or bronchitis, rather than the specific allergic response involved in rhinitis.
