Multiple Choice

Which TB regimen duration corresponds to 3 months?

Explanation:
The key idea is to identify the regimen that lasts exactly three months. The only option that has a total duration of three months is the combination of rifampin and isoniazid given together for three months. The other choices show durations of four months or nine months, which don’t match three months. In TB treatment, using more than one drug together helps prevent resistance and improves efficacy, but for this question the focus is simply which regimen equals a three-month duration.
