**Core Concept**
Exercise-induced asthma is a type of bronchial asthma triggered by physical activity, leading to airway constriction and symptoms such as wheezing, coughing, and shortness of breath. This condition is caused by the release of bronchoconstrictor substances, including histamine and leukotrienes, from mast cells and eosinophils in response to exercise.

**Why the Correct Answer is Right**
The correct management of exercise-induced asthma involves the use of inhaled corticosteroids (ICS) or bronchodilators before exercise to prevent symptoms. ICS work by reducing inflammation in the airways and suppressing the release of bronchoconstrictor substances, while bronchodilators, such as beta-agonists, help to relax the airway muscles and improve airflow.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not address the root cause of exercise-induced asthma, which is the release of bronchoconstrictor substances from mast cells and eosinophils. Simply avoiding exercise is not a viable solution for managing this condition.

**Option B:** This option is incorrect because it does not specify the type of medication or the timing of administration. While medication is an essential component of managing exercise-induced asthma, the type and timing of administration are crucial in preventing symptoms.

**Option C:** This option is incorrect because it does not provide a clear solution for managing exercise-induced asthma. While staying hydrated and avoiding triggers may be beneficial for overall health, they do not specifically address the symptoms of exercise-induced asthma.

**Clinical Pearl / High-Yield Fact**
A key aspect of managing exercise-induced asthma is to identify and avoid specific triggers, such as cold air, dry air, and air pollution, which can exacerbate symptoms.

**Correct Answer:** D.
