Select and explain. 
A. It inhibit lipooxygenase pathway, B. It blocks LT receptor, C. It can be administered orally, D. All of these
D: All of these
Answer: D: All of these 
Explanation: Zafirlukast and montelukast are cysteinyl leukotriene receptor antagonists. They cause modest improvement in lung function and reduction in asthma symptoms and lessen the need for beta-agonist rescue therapy. These drugs can be considered as alternatives to low-dose inhaled corticosteroids in patients with persistent asthma.
Zafirlukast is long-acting and can be given twice to once daily orally. It is a modest bronchodilator that reduces asthma morbidity, provides protection against exercise-induced asthma and diminishes nocturnal symptoms.
These are less effective than corticosteroids.
