- D A person with confirmed Mycobacterium tuberculosis on CBNAAT
Correct answer: A. Any person who has any one of: cough ≥2 weeks, fever ≥2 weeks, significant weight loss, or haemoptysis
Explanation
Under NTEP (aligned with NIKSHAY), a 'TB Presumptive case' is any person presenting with one or more of: cough ≥ 2 weeks, fever ≥ 2 weeks, significant unexplained weight loss, or haemoptysis. These patients are eligible for diagnostic workup. A TB case is confirmed by microbiological evidence (CBNAAT/smear/culture). The presumptive case definition broadens the gate for screening and diagnosis.
