b.It is an antibiotic that cures the underlying asthma

Giải thích
Albuterol is a short-acting bronchodilator that relaxes smooth muscle in the airways, producing rapid relief of wheezing and shortness of breath during an asthma flare. Asthma is not a bacterial infection, so antibiotics have no role. Slowing respiration would worsen an attack, and rescue inhalers do not replace controller medications prescribed for long-term management.
