Correct answer: B — Residual nucleic acid can cause an early false-positive

NAAT can remain positive from non-viable organisms for several weeks after successful treatment, so an early test may mislead. Assess adherence, vomiting and re-exposure; when test of cure is indicated, perform it at the recommended later interval. Partner management remains essential.
