الإجابة: C. Latent TB
A positive TST in a well, asymptomatic person with a normal chest X-ray = latent TB infection. Active pulmonary, miliary or extrapulmonary TB would cause symptoms and/or an abnormal CXR, and they would be diagnosed by AFB smear/culture, not by TST.

A
ليش غلط
An asymptomatic person with a positive TST and a normal chest x-ray fits latent TB (no signs of active infection), not extrapulmonary TB; the TST itself does not separate active from latent TB.

B
ليش غلط
Active pulmonary TB would show an abnormal chest x-ray (which triggers work-up for active TB) and symptoms; latent TB is asymptomatic with a normal film.

C
ليش صح
A positive TST with a normal chest x-ray means latent TB, which fits this well, asymptomatic person.

ليش غلط
An asymptomatic person with a positive TST and a normal chest x-ray is treated as latent TB; only an abnormal film leads to work-up for active disease such as miliary TB.
