Answer 1

The Correct Option is B

In the context of tuberculosis treatment, the first-line drugs are those that are most effective and least toxic. Among the provided options, let's evaluate their relevance for tuberculosis:

• Amoxicillin: This is a penicillin-type antibiotic effective against a range of bacterial infections, but it is not used for tuberculosis.
• Isoniazid: This is a highly effective antibiotic specifically used as a first-line treatment for tuberculosis. It targets the bacteria causing the disease and is part of the standard treatment regimen.
• Ciprofloxacin: An antibiotic used for different bacterial infections but not typically a first-line treatment for tuberculosis, though sometimes used in resistant cases.
• Azithromycin: Another antibiotic effective against various infections but not used for tuberculosis treatment.

The correct answer is: Isoniazid, as it plays a crucial role in the initial treatment of tuberculosis by specifically targeting the Mycobacterium tuberculosis bacteria.
