Answer:
The correct answer is (b) epinephrine.
Explanation:
Epinephrine, also known as <em>Adrenaline</em>, is a hormone secreted by the medulla of the adrenal glands.
In medicine, epinephrine is used as a stimulant in cardiac arrest, as a vasoconstrictor in shock and as a bronchodilator and antispasmodic in bronchial asthma.
When epinephrine is inhaled in small doses, it causes short-term relief from the symptoms by widening the bronchial tubes allowing air to pass through.
I hope it helps!
