Correct answer: C — An owing balance may be supplied later within the 28-day validity period

A partial supply of a controlled drug may be made when stock is insufficient, but any remaining balance must be supplied within the prescription validity period. Schedule 2 CD supplies and balances require appropriate record-keeping. If the balance cannot be obtained in time, the prescriber may need to issue a new prescription.
