A 28-year-old pregnant woman has gonorrhea. The most appropriate treatment would include ceftriaxone to eliminate gonococci plus another drug given presumptively to eliminate Chlamydia. The antichlamydial agent would act by
A. binding to the 30S ribosomal subunit, thereby preventing attachment of the aminoacyl tRNA to the acceptor site
B. binding to the 30S ribosomal subunit, thereby preventing formation of the initiation complex
C. binding to the 50S ribosomal subunit, thereby inhibiting peptidyltransferase activity
D. binding to the 50S ribosomal subunit, thereby preventing translocation of peptidyl tRNA from the acceptor site to the donor site
E. inhibiting transpeptidase, thereby preventing the cross linking of the bacterial cell wall
