Expert Solution

Bronchodilators has been used to treat asthma. These medications are adrenergic agonists. The stimulation of adrenergic beta receptors in the bronchial smooth muscle cause bronchodilation and helps with asthma.

The alpha adrenoreceptors in the pancreatic islets inhibit the production of insulin, the hormone responsible to reduce blood glucose level. The beta adrenoreceptor stimulation increases the production of glucose in the liver.

Thus the answer is b. Alpha and beta receptors activation.
