The correct option is A All of the above
Glucocorticoids are a class of steroid hormones, that bind to the glucocorticoid receptors. They are a part of the feedback mechanism in the immune system that turns immune activity or inflammation down. They are therefore used in medicine to treat diseases caused by an overactive immune system, such as allergies, asthma, autoimmune disease and sepsis.
Thus, the correct answer is option (D), 'All of the above'.
