Final answer:
The appropriate antibiotics for treating tubo-ovarian abscess in pelvic inflammatory disease are clindamycin and gentamicin.
Step-by-step explanation:
Tubo-ovarian abscess (TOA) is a serious complication of pelvic inflammatory disease (PID) and requires treatment with antibiotics. The most appropriate antibiotics for treating TOA in PID are clindamycin and gentamicin (option d).
Clindamycin is a lincosamide antibiotic that provides coverage against anaerobic bacteria, including those commonly found in abscesses. Gentamicin is an aminoglycoside antibiotic that has activity against gram-negative bacteria. The combination of these two antibiotics provides broad coverage against the organisms commonly involved in TOA.
