Hint: Asthma is a condition in which a person's airways become inflamed, narrow and swell and create additional mucus, making it difficult to breathe.

Complete answer:
Normally, air goes through your nose or mouth and down through your throat and through your airways for every breath you take, ultimately making it to your lungs.
In your lungs, there are tonnes of tiny air passages that help carry oxygen from the air into your bloodstream.
Symptoms of asthma arise when the lining of the airways swells and the muscles contract around them. The airways are then filled with mucus, further decreasing the amount of air that can move through.
Inflammation of the lungs and spasms in the bronchial muscles cause asthma.

Signs & symptoms of asthma include:
1.Shortness of Respiration
2.Tightness in the chest or discomfort
3.Wheezing, which is a common sign of asthma in children, while exhaling
4.Sleeping problems related to shortness of breath, coughing or wheezing
5.Coughing or wheezing attacks, such as a cold or flu, that are exacerbated by a respiratory virus

Signs and symptoms of asthma may be caused by exposure to multiple irritants and substances that cause allergies (allergens). Triggers of asthma vary from person to person and can include:
1.Allergens in the air, such as pollen, dust mites, mould spores, pet dander, or cockroach waste particles
2.Infections of the immune system, including the common cold
3.Physical exercise
4.Cold weather Cold air
5.Irritants and air contaminants, such as smoke,
6.Certain medicines, including beta-blockers, aspirin, and anti-inflammatory nonsteroidal medicines, such as ibuprofen (Advil, Motrin IB, others and sodium naproxen (Aleve)
7.Strong feelings and stress
8.Some kinds of foods and drinks, including seafood, dried fruit, processed potatoes, beer and wine, are added to sulfites and preservatives
9.Gastroesophageal reflux disease (GERD), a condition in which acids in the stomach return to the throat
Hence, the correct answer is option (D)

Note: Asthma therapies fall into three main categories:
1.Respiratory exercises
2.Treatments for fast-acting
3.Medications to regulate long-term asthma
