Correct answer: A — Add an indelible dated marginal note or footnote identifying the correction while leaving the original entry legible
A controlled-drug register entry must not be cancelled, obliterated or altered. A correction is made by a dated marginal note or footnote that preserves the original and the audit trail; electronic systems must provide the equivalent traceability. Deleting, overwriting, correction fluid or silently changing only the balance obscures the original transaction and fails the statutory standard.
