The answer is c, Chlamydial urethritis.

Urethritis in an adolescent male is almost always a sexually transmitted disease (STD), either gonococcal or nongonococcal urethritis (NGU). Chlamydia trachomatis is usually the causative agent in NGU. Less frequently, NGU can be caused by Ureaplasma urealyticum, Trichomonas vaginalis, and yeast. Herpes simplex can cause an NGU, but it is considerably less likely than C. trachomatis. Gonococcal culture and Gram stain are easily available; chlamydial culture may not be. Direct monoclonal antibody tests as well as enzyme immunoassay and molecular probe tests are alternative methods for Chlamydia identification, although they are less sensitive and less specific than chlamydial culture. Urine ligase testing for chlamydia and gonococcus is available. Serologic testing for syphilis should always be done, but in none of its normal presentations is urethral discharge common. Testing for HIV should be offered and safe sexual practices encouraged; HIV does not cause urethral discharge. Urinary tract infection is not associated with a urethral discharge.
