The key is A. PCR for treponomal and non-treponemal antibodies. [Non treponemal antibody test if
positive indicate that there may be syphilis and it is not confirmatory alone. That is why treponemal
antibody test should also be done to confirm it. On the other hand resolved disease may show negative
treponemal test which is confirmed by positive non-treponemal test].
