Antihistamines are the primary drugs used for treating allergic rhinitis due to their ability to counteract histamines responsible for allergy symptoms.
Antihistamines are the drugs of choice for allergic rhinitis. These medications work by reducing or eliminating the effects of histamines that cause allergy symptoms, such as nasal congestion and sneezing.
Antihistamines are commonly used for treating mild allergic reactions and are available in both prescription and over-the-counter forms. They are usually recommended for short-term use and can be combined with other anti-inflammatory agents for a more effective treatment regime.

Answer:
Option B, antihistamines
Explanation:
Allergic rhinitis, also known as hay fever, is a condition in which environmental allergens, typically airborne, trigger mild allergic reaction symptoms such as inflammation of the nasal passages, sneezing, pruritus (itching), eye watering, congestion, runny nose, headache, increased sinus pressure, and other symptoms that may mimic the common cold (infective rhinitis).
Because an allergen is the causative agent, the treatment and management usually begins with an antihistamine medication, such as diphenhydramine (brand name Benadryl), loratadine (brand name Claritin), cetirizine (brand name Zyrtec), etc. These medications block the release of histamine that is signaling for the immune system response. The allergen itself cannot be blocked pollen, dust, and pet hair cannot be fully eradicated; therefore, blocking the response to such allergens becomes the go-to plan of care.
If the patient is experiencing a nasal congestion, sinus congestion, and postnasal drip, they may also receive decongestant medications to relieve these symptoms, such as pseudoephedrine (brand name Sudafed) and oxymetazoline (brand name Afrin).
In selecting only one, however, the drugs of choice for allergic rhinitis are antihistamines, option B.
