In pharmacokinetic models, the term “compartment” means:

Match List I with List II

	List I		List II
A	When two dosage forms have equal t max	I	When their total body clearance is constant.
B	AUC values of the two analogs can be compared to measure relative bioavailability	II	Absorption rate constants are equal
C	Urinary data is valid to measure bioavailability. III. W	III	When fraction absorbed and elimination rate is constant.
D	C max is proportional to the rate of absorption	IV	Excretion of drug and/or metabolite is related to the bioavailable dose.
