Final answer:
Salmeterol and Formoterol are considered Long-Acting Beta Agonists (LABAs), which are typically used for the long-term control of asthma and chronic obstructive pulmonary disease (COPD).
Step-by-step explanation:
The medications considered Long-Acting Beta Agonists (LABAs) among the options given are Salmeterol and Formoterol. Albuterol and Levalbuterol are short-acting beta agonists (SABAs) and would not be classified as LABAs. Ipratropium is a short-acting muscarinic antagonist (SAMA), and Vilanterol is indeed a LABA but it is not paired with another LABA in the options provided. Therefore, the correct answer is d. Salmeterol and Formoterol.
