According to MARPOL, the definition of medical waste does NOT include __________.

Correct Answer: Option C — expired pharmaceuticals

MARPOL Annex V defines medical waste as waste generated by medical activities, including dialysis, pathological, and sharps. Expired pharmaceuticals are generally classified as chemical waste or hazardous materials rather than medical waste, as they do not typically pose the same infectious risk profile as clinical sharps or pathological samples.
