Option A is not entirely accurate because bacteria cannot become immune to a drug as it is commonly understood to mean natural immunity to an infection. Option B is not entirely accurate because drug resistance is not due to the body adjusting to the chemical dosage, but rather the microorganisms adapting to the drug treatment. Option C is only partially accurate because while some drugs may become inactivated in the body, drug resistance refers to the microorganism's ability to withstand the drug's effect. Option D is the most accurate because it describes the physical and chemical changes that occur in the microorganism, allowing it to avoid or destroy the drug's action. This definition encompasses the various mechanisms of drug resistance, including changes in the drug target, efflux pumps, and enzymatic inactivation.
